Chris Evans' heart isn't "in" superhero sagas as it was.
The 32-year-old actor - who is set to hit the big screen in 'Captain America: The Winter Soldier ' - is glad he starred in the Marvel films but admits he no longer has as much passion for the franchise as he once did.
He said: "I would never trade in the decision to have done these movies. I've been wildly fortunate. I just don't know if my heart's as in it as it once was."
The hunk plays the titular character, who is also known as Steve Rogers, in the sequel to 2011's 'Captain America: The First Avenger' and feels he can relate to his alter-ego.
He told GQ magazine: "Steve has everything he wanted, and he's still not quite happy. It's like he's in his adolescence, trying to figure out where he fits in, who he is and what he wants."
Evans hinted he'd step back from fronting films and would prefer to be involved in the filmmaking process because he isn't a fan of the additional responsibility an actor is forced to undertake.
He added: "I would imagine the world of a director is a little bit cleaner in terms of your responsibilities."

Dannii Minogue says people get "confused" between her and her sister Kylie.
The fashion designer has admitted some of the public still struggle to tell the difference between the two famous siblings when they see them "in real life".
She told the Daily Star newspaper: "People get us confused all the time. I think when people see us together in real life they can't believe how similar we look.
"We want to the BRITs together last month and everyone kept staring. They'd look at one of us and then back to the other. No-one knew what so say."
She thinks it works both ways, but she's "never asked" the 'I Should Be So Lucky' hitmaker if people mistake her for Dannii.
She added: "I imagine she gets people thinking she's me too, but I've never asked her."
Meanwhile, Dannii recently admitted she has a worm farm because she "can't take care" of any other pets due to her hectic career.
She said: "You're exposing stuff that you're into that people don't know. I was telling Reggie [Yates] earlier that I have worms.
"I have a worm farm. Other pets I can't take care of because I'm travelling between London and Melbourne."

Leonardo DiCaprio has invited Harry Styles to hang out and talk about potential acting roles.
The 'Wolf of Wall Street' star wants to spend some time getting to know the One Direction hitmaker, and it is said his production company is willing to offer the singer a number of movie parts.
An insider told The Sun newspaper: "Leo's production company Appian Way has at least ten movie projects in the works with roles that could interest Harry.
"Leo's invited Harry over to his house for a long weekend when their schedules allow to talk work and women. Bradley Cooper will probably be around too."
Fans concerned about the future of the 'Story of My Life' boyband shouldn't be too worried though after the group went on record to dismiss rumours they could split up to pursue solo careers.
Harry recently said: "We're not breaking up. We've spent every day together for months and forgot what my mum looked like. It's just holidays."
His band mate Liam Payne has also rubbished claims of an imminent break-up, pointing out they have already started work on their fourth album.
He added: "We have been writing away for the next album and rehearsals are just about to start soon for the tour. We're not splitting up.
"We're on WhatsApp messaging each other all the time, talking about song ideas and just funny stuff from our day.
"It's been a while since we have all been together so we are enjoying being back in each other's company."

Robin Thicke has vowed to save his marriage to Paula Patton.
The couple recently announced their split, but the 'Blurred Lines' singer has told fans they should always "fight" for the person they love "no matter what".
Speaking to fans at a New York gig at Madison Square Garden last night (07.03.14), Robin said: "When there's someone you love, you gotta fight for them no matter what."
Robin has been opening up to fans a lot while he's on the road, and recently told fans in Atlantic City that he was trying to spread "love and joy".
He said: "Never stop believing and you never stop loving. And even if it is over, make sure you treat each other right. Treat your family right. Take care of your mom, take care of your kids and good things will come to you. Just keep believing that God is good.
"That's what gets me by. Sometimes when I get a little scared or worried about the future, I just try to stay positive and do my part to spread love and spread joy."

Ellie Goulding used to take drugs when she was a goth.
The 'Burn' hitmaker has admitted she used to be a compete contrast to her current innocent, blonde bombshell image, explaining she used to be "a bit of a rebel".
She told Sir Michael Parkinson about hearing a life on the streets, and said: "I very nearly did go down that path. I was a bit of a rebel when I was 14.
"People would call me a goth. I had long black hair which was real. I had piercings and liked heavy metal music, and the rest of it."
Meanwhile, when the presenter - interviewing Ellie for the upcoming series of 'Masterclass' - responded, "And drugs"?
She replied: "Yeah. I definitely had a period of drinking and being a bit crazy. I had no idea what my future was going to be then."
Ellie, 27, also admitted being in the public eye has meant she was "very insecure" about her about her looks, and initially she struggled to cope with the pressure.
She said: "I felt for a long time that I had to be really skinny and looking good. And when i finally realised that was what it was about, I stopped caring.
"I did become very insecure. I never came into this to become a pretty pop star but all of a sudden I was being talked about for what I was wearing, for my nose, my chin.
"I didn't ask for that but people assume because you are in that position that is what you want."

Jessica Paré says 'Mad Men' changed her life.
The 33-year-old star was an unknown actress before she landed the part of Megan Draper on the AMC series and she claims the show has made things much better for her.
She said: "Everything changed. Like, I was able to pay rent. And I had this old car. The engine had rusted though and the wheels were going to fall off. It was really bad..."
'Mad Men' will come to an end following the seventh and final series later this year and Jessica is going to miss working alongside actors including Jon Hamm and January Jones, but is thankful for everything the show has done for her career.
She said: "It's been such a big part of my life. Before I got the role I was having a hard time getting work and just in life, so it's been such a ride.
"It's a dream job for an actor. It's so well written and they are an amazing group of people to work with. We're very tight. We genuinely enjoy each other's company."
Jessica says her next aim will be to star in an action or a romance film but admits she'd like to try all genres - apart from the more extreme ones.
She explained to Stylist magazine: "I'd like to do an action movie and then do a romance. I'd like to try it all. Basically, I like all genres with the exception of torture porn."

Jay Z has turned down the chance to be Kanye West's best man.
The 44-year-old rapper only agreed to the idea initially providing his family - including wife Beyonce and their two-year-old daughter Blue Ivy - wouldn't be filmed for Kim Kardashian's reality show.
Speaking to the Daily Star newspaper, an insider revealed: "Jay is Kanye's closest friend so he wants him to be best man.
"Jay agreed initially but had one condition - under no circumstances can there be any reality TV shows filming him, his wife, Beyonce or daughter Blue Ivy during the ceremony."
Meanwhile, Jay Z's wife is also said to be totally against appearing on 'Keeping Up With The Kardashians'.
The source added: "The thought of popping up in 'KUWTK' mortifies Beyonce.
"She purposefully keeps herself away from trashy TV and isn't prepared to lower her standards for anyone, or any occasion."
However, E! bosses - who run Kim Kardashian's reality show - are reportedly "desperate" to air the ceremony, meaning Jay Z may miss out on being best man.
The insider said: "Bosses at E! are desperate to get the nuptials on air, and will pay millions to make it happen."

Blake Fielder-Civil's mother "made excuses" for his and Amy Winehouse's drug use.
The late singer's former mum-in-law Georgette Civil has admitted she defended the 'Back To Black' hitmaker and her son, become his "enabler".
Speaking about first meeting Amy, she explained to The Sun newspaper: "Amy looked glowing. She threw her arms around me and said, 'Isn't our boy handsome?' I adored her.
"But later, we all sat at dinner and Amy kept ducking under the table. Then Blake said, 'You'd better go to the bathroom', and she went upstairs. [My second husband Giles] turned to Blake and bluntly asked him, 'Are you doing drugs?', but I reacted furiously, saying, 'Of course he isn't'.
"From that moment, I became Blake's enabler - making excuses for him and Amy."
Indeed, Georgette revealed she "wasn't strong enough" to accept Blake's cry for help, despite the singer - who died of accidental alcohol poisoning in July 2011 - inviting her for a meeting at a hotel.
She said: "One day, Amy invited me to another hotel where she and Blake were staying. He sat at the table and said, 'Mum, I have a dependence and need help. There's been times I've spent £600 a day on heroin.
"I took him in my arms and said, 'You are talking nonsense'. I t was his only cry for help - but I wasn't strong enough to face the truth ... It was only later that I suddenly realised that Blake was a hopeless addict.
"But by then, I was caught up the lies and deceit myself - and it was too late to save Amy."

Dannii Minogue says Cheryl Cole will thrive as the only female judge on 'The X Factor'.
The pair were on the panel together in 2008, and the fashion star has backed the former Girls Aloud singer to be a huge success if she does decide to return to the TV talent show.
She told The Sun newspaper: "I don't know what's going on with the panel but if Cheryl does come back as the only girl I don't think she'll miss female company too much.
"I liked the fashion wars but Cheryl will have more than enough glamour and frocks to do it on her own.
"And she can definitely hold her own with just the boys. I think she'll love it."
It has been said that Cheryl told show bosses she wants to "be the only woman" judging on the show, and as negotiations continue she "seems to be calling the shots".
An insider recently said: "If Cheryl does come back as planned, she will be the only woman on the panel. That's how she wanted it and at this moment she seems to be calling the shots.
"They're still finalising the other details but Cheryl made it clear she didn't want to be pitched against another female again."

'Sherlock' creator Mark Gatiss says Benedict Cumberbatch is irreplaceable.
The show's boss admitted the programme would not be able to continue without its leading man in the role of the fictional detective, and insisted both he and Martin Freeman are vital to its success.
Speaking to the Daily Mirror newspaper, he said: "If Benedict went under a bus tomorrow it would be the end of the show.
"Benedict and Martin are our stars. We do three episodes a year and although people want more that's all we can do. They are so famous now it's difficult to get them."
Mark recently responded to criticism at fans having to wait until 2016 for new episodes - due to their two lead actors having very busy schedules - and point out the gap between series is "always" a similar length.
He explained: "Everyone wants to carry on doing 'Sherlock'. It's a simple matter of schedules - particularly Benedict and Martin.
"They've become superstars, which is brilliant, but we all want to carry on as long as we can.
"There was suddenly a kind of outraged response that it might not be back until 2016 but that's precisely how long it always is. It's always two years! But we'd like to return soon, of course."

Paloma Faith feels like a "competition winner" because of her high-profile collaborators.
The 'Can't Rely On You' singer has worked with a string of famous faces on her new album 'The Perfect Contradiction' and can't believe stars like Pharrell Williams and Raphael Saadiq wanted to write with her.
She said: "On this album I didn't approach hardly any of the people, I met Pharrell at the Met Ball [last year] and came up and asked to work with me, which I was gobsmacked about. He came up to me and was like, 'I think you're so cool' and was singing my songs to me. I was just like, 'How do you even know who I am?'
"Raphael I met because I was opening for Prince and he was as well, he was like 'Let's write together.'
" I feel like a competition winner."
Paloma admits she found it hard to concentrate when she entered the studio with Pharrell because she was so in awe of his youthful good looks.
Asked what it was like entering the studio with him, she said: " Difficult to concentrate because he's so beautiful and I can't believe he's 43, he looks about 15. And his wife is devastatingly beautiful. He's nice and humble."
Though they got on well, the 32-year-old singer admits she hasn't heard much from the 'Happy' hitmaker recently.
She joked in a radio interview: " I've got his phone number and email. He's quite busy now, he doesn't reply as much as he used to. I think I'm left out on the doorstep."

Cameron Diaz spent days with Jason Segel's "package in her face" making 'Sex Tape'.
The pair star in the comedy series about a couple who video themselves recreating the Karma Sutra - a famous ancient Indian sex manual - only for it to go missing, and filming the initial scenes required a certain level of intimacy between the co-stars.
Cameron told People magazine: "[We] got to know each other very well. Our day was, 'My butt is going to be in your face, your package is going to be in my face."
Despite the raunchy subject matter, the health conscious star says the shoot was one of the most fun she's been on.
She added: "[It was the] funniest job I've ever had. It was highly athletic. Jason and I had to keep our strength up."
The 'Bad Teacher' star has recently written 'The Body Book' and through learning about her body she recently urged women to take better care of their private parts and treat their genitals like "beautiful flowers".
She said: "We think the vagina is on the outside. I say grab a mirror and play along. Get in there.
"Learn about it. You're supposed to treat it like the beautiful flower that is, the delicate flower that it is. And you're supposed to nurture it in all the ways that it needs nurturing. Watering it. Fertilising it. It needs nourishment. It's hungry."
