'Interstellar' is an "evolution" in filmmaking for Christopher Nolan.
The acclaimed director assembled an all-star cast for the movie - which follows a team of space travellers as they go through a wormhole - and despite the scale of the production, its star Matthew McConaughey insists it is very "intimate".
He said: "Nobody is able to put more scope, scale, awe on screen than Chris.
"But I think he was wanting to take the next step, toward something more intimate. It was an evolution."
For the director, who wrote the script with his brother Jonathan, he wanted to make an "honest" film about "human nature" and the way people interact.
He explained in an interview with Entertainment Weekly magazine: "The film is about human nature, what it means to be human. It sounds like a very grand statement, but I don't intend it to be. I mean it in the way, say, 'Treasure of the Sierra Madre' is about dramatising ideas of human nature.
"When you take an audience far away from human experience as possible, you wind up focusing very tightly on human nature and how we are connected to each other. What the film tries to do is to be very honest in that appraisal."

Simon Cowell is planning a worldwide 'Britain's Got Talent'.
The music mogul is interested in expanding the ITV talent competition show's format - which has been sold to nearly 150 different territories - into a global entertainment challenge, similar to the Eurovision Song Contest.
Speaking about the idea of a "pan-regional entertainment format", Simon said: "That is something we have been thinking of for more than three years, a long time."
The idea is that countries would select their best act - from singers to dancers to talented pets - and then vote for their favourite acts to make it into the grand final.
However, Simon insists it will not follow the format of his other hit talent show 'The X Factor', because that failed to work in the past.
He explained: "There were something like 16 judges on that show, so the judging took about half an hour on each act, and every one of them had been put on the show to be the equivalent of me. It was who could be ruder each time. It was just a disaster."
The 55-year-old star added to the Independent newspaper: "The 'Got Talent' format would be the most obvious one to start with. We'll definitely be in that space sooner rather than later."
Meanwhile, Simon also confessed he and his Syco Entertainment company are in discussions about a possible Netflix-style web streaming service.
He said: "We are going to announce something soon that is going to be a big show and it is not on a cable network... I think it is hopefully a bit of a game changer because the market has suddenly just got bigger."

Heston Blumenthal is "not fighting" with his wife despite being four years into their divorce proceedings.
The 48-year-old TV chef has revealed that although he's been in the process of divorcing wife Zanna Blumenthal - with whom he has children Jack, Jessie and Joy - for four years, the delay has been caused by their business affairs rather than personal issues.
He explained: "Although I'm four years into a divorce, it's the financial side - a complicated administrative thing. We're not fighting. It's just gone on for a long time because we were looking at the company restructuring and it's all tied into that.
"Dull, boring and complicated stuff."
Heston - who is now dating Suzanne Pirret -also spoke about a photograph in which he is seen cosying up to 'Top Gear' presenter Jeremy Clarkson to raise money for UNICEF.
He told The Times newspaper: "It was at [the broadcaster] Richard Bacon's house. We were talking about the 'selfie for Syria' thing and Bacon says, 'Right, come on, you two, let's do this. I want you spooning!'
"We looked at each other, and at the same time we said, 'We're not frigging spooning'. We took our shirts off - we weren't naked. I went like this and knocked my glasses to one side ... But one article described me as, 'A rather bedraggled looking Heston', like something had actually gone on, Ha! Ha!"

Jodie Marsh has slammed Essex Police following threats on her life.
The glamour model turned bodybuilder took to Twitter today (15.10.14) to express her relief that authorities had stepped up to support Judy Finnigan's daughter Chloe Madeley after she was trolled for comments her mother made regarding rape on her ITV panel show 'Loose Women', but claims she has received no such help.
Jodie, 35, attacked the force directly on the social media site claiming they had done nothing to protect her over the past two years, throughout which she has received countless threats on her life.
She wrote: "I'm very happy that the police are taking @MadeleyChloe threats seriously but it does make me wonder why @EssexPoliceUK won't help ME....
"I've been getting death threats for the best part of 2 years & I'm terrified. I know who it is & I'm scared when out at events.
"When I did that charity abseil a while back, my stalker threatened to cut the rope! @EssexPoliceUK told me to "stay indoors".
"I have lost ALL faith in @EssexPoliceUK and I'm still scared for my life. My security measures have quadrupled & I rarely go out.
"I've been told by @EssexPoliceUK there's nothing more they can do even though I am STILL getting death threats from the same person. (sic)"
Jodie feels so let down by the Essex police force she confessed she has even considered moving out of her home.
She said: "Being totally honest, it makes me want to move abroad. I don't feel safe anywhere knowing this person is watching me & out there!"
The Brentwood-born star added she is grateful for her "inner strength" which has helped her get through the "worst two years" of her life.
Jodie said: "I'm thankful I'm a strong woman tbh. I would not be getting through each day without my inner strength. It's been the worst two years."

Olly Murs has slammed Taylor Swift for writing songs about Harry Styles.
The former 'X Factor' star has hit out at the 24-year-old stunner, whose latest song 'Out of the Woods' is rumoured to be about her One Direction singer ex-boyfriend - who she dated for three months before their January 2013 split - and called on her to write "something new" that isn't about him.
Speaking on Australian radio station 2DayFM's breakfast show, Olly said: "Come on [Taylor], let it go. Write something new that isn't about Harry.
"Bless him, it's been like two years and he's still getting lashed out isn't he?"
As well as blasting the 'Shake it Off' star, Olly also poked fun at the singing sensation - who has sold more than 30 million albums and 75 million digital downloads - by performing a section of 'Out of the Woods' but changing the lyrics slightly to include the line: "I remember all I remember."
He sang: "You were looking at me, you were looking at me, I remember all I remember
"Are we out of the woods yet? Are we out of the woods yet? Are we out of the woods yet?"
In the original song, which is about a death-defying snowmobile crash Taylor had with an ex-boyfriend resulting in them having to get stitches in hospital, the star sings: "I remember.
"Are we in the clear yet?
"Are we in the clear yet?
"Oh, I remember.
"Are we out of the woods yet?"
What's more, Taylor is rumoured to have written other songs including 'I Knew You Were Trouble' - from her fourth studio album 'Red' - about Harry.
She performed another hit single from the album, 'We Are Never Ever Getting Back Together' - which is rumoured to be have been penned about her ex-boyfriend Jake Gyllenhaal - at the Grammy Awards in 2013 and appeared to make a sly dig at Harry, who was sitting in the audience.
Taylor poked fun at him by putting on a British accent as she said the song's line: "So he calls me up and he's like, 'I still love you' "
Despite the countless rumours, Taylor - who is set to release her fifth studio album '1989' later this month - has never said, and has insisted on many occasions she won't ever say, who her songs are aimed at.
Olly became friends with One Direction after they competed on 'The X Factor' in 2010, one year after he finished second on the talent show, but he recently revealed they tell him they are "too busy" to attend his parties.
He said: "I always invite the 1D boys to my BBQs but they're too busy."

The 25-year-old actress has been working non-stop recently but when she does get some time off from shooting movies she likes nothing more than finding bargains at cheap sales and then heading home for game nights with her friends.
Speaking about what she does in her free time, she said: "I still love going to the movies. I go to flea markets a lot and my friends and I bake and cook. I'm big on game nights. I love having people over."
Lily's parents are British musician Phil Collins and his second wife Jill Tavelman and although she was raised in Los Angeles by her American mother in the wake of her parents split she admits she often yearns for the UK.
In an interview with Metro newspaper, she said: "I feel more European than American. I have to come back to the UK and get my fix for cold, tea and fire."

Brad Pitt and Angelina Jolie's kids "like" the fact they are married.
The couple tied the knot in August on the urging of their children Maddox, 13, Pax, 10, Zahara, nine, Shiloh, eight, and six-year-old twins Vivienne and Knox and their famous father says the brood are thrilled the union is now official.
Asked how the children are enjoying their parents being married, Brad smiled and told People magazine: "They like it. They like it."
To prepare for his new movie 'Fury', Brad and his army tank co-stars, including Shia LaBeouf, Michael Pena and Logan Lerman went put through bootcamp by Navy SEALS and part of the tough training involved being sleep-deprived.
Each of the stars had to stay awake on watch each night and it fell to the youngest member of the crew, 22-year-old Logan, to wake Brad, 50, each night and he found it was important to do so with "tenderness" and a gentle kiss.
Logan said: "We each had to wake the next person, and the next person was Brad for me. So I had to be the guy to wake Brad Pitt up.
"It was weird. How do you wake up a sleeping beauty? It took a while to figure it out. You just kiss him gently and you rock him and you hold him and you say, 'Hey, sweetie.' "
Asked to seriously answer how to wake Brad, he laughed and said: "I told you. Tenderness. Be kind."

Zoe Saldana will give birth in eight weeks.
The 'Guardians of the Galaxy' actress - who is expecting twin boys with husband Marco Perego - is "feeling great" but constantly hungry.
She said: "I still have a ways to go. We have maybe eight more weeks or something. I feel great.
"I'm hungry all the time! I have to say, nothing makes me happier than to see a pregnant woman eat. Especially in LA!"
Tucking into a food tray provided by 'Late, Late Show' host Craig Ferguson, the 36-year-old beauty insisted she hadn't experienced any cravings during her pregnancy but had found food tastes better than ever.
She told the presenter: "You'd be surprised -- I'm just hungry. It feels good. Food just tastes so delicious. It really does. It's really good. You trick yourself, working in Hollywood, going, 'That burger's disgusting. A burger's awful.'
"But now that [I'm] pregnant [I'm] like, 'I could eat all this --together -- at the same time.'
"Like, I could have the pickle with the donut and it would probably be life changing."
And Zoe admits there is nothing she likes more than being told how "sexy" she looks with her growing baby bump.
She said: "The best thing a pregnant woman can hear is the word 'sexy.' It's like, 'Oh, you think I'm sexy? Yes! I'm sexy.' You know?
"Usually I'm an activist and [a supporter of] women's rights. I'm like, 'Excuse me, do not objectify me!' or whatever, but now that I'm pregnant, I'm kind of itching for sexy compliments."
While she isn't experiencing any unusual cravings, the 'Avatar' actress has developed an obsession with TV murder mysteries.
She said: "In the middle of the night I don't wake up with cravings. I've been watching a lot of crime shows, though.
"I don't know why. Murder mysteries. I'm solving the case and it's like 2 o'clock in the morning because that's one of the gifts of being pregnant -- sometimes you just can't sleep.
"So, I find myself watching '48 Hours Mystery' or 'Dateline' with Lester Holt. My husband wakes up and I'm just like, 'He totally did it! She did it!' "
