Joss Whedon says Ultron is "everything a robot never is".
The 49-year-old director is working on ‘Avengers: Age of Ultron’ and he’s been having a "blast" developing the character which is played by James Spader.
He explained to Empire magazine: "I’m having a blast with Ultron.
"He’s not a creature of logic – he’s a robot who’s genuinely disturbed. We’re finding out what makes him menacing and at the same time endearing and funny and strange and unexpected, and everything a robot never is."
Spader joins an A-List cast including Robert Downey (Iron Man),
Chris Hemsworth (Thor), Mark Ruffalo (The Hulk), Chris Evans (Captain America), Scarlett Johansson (Black Widow), and Samuel L. Jackson (Nick Fury).
Although there a number of big names Whedon insists every character in the forthcoming epic has a significant role to play.
He explained: "I fiercely dislike the idea of just throwing in more people for the sake of doing that.
"But last time I had all of Earth’s Mightiest Heroes versus one British character actor, and I needed more conflict."
The filmmaker wants to bring a different aesthetic to the picture to make sure it isn’t too similar to 2002’s ‘The Avengers’.
He added: "The number of different looks and textures and moods we’re getting from the British locations is stupid awesome, because this, palette-wise, is very different. I’m trying to make a different film. Because why would you make one movie twice? That seems weird."
