Joss Whedon says Ultron with 'juice things up' and be a 'real problem' in Avengers: Age of Ultron.
The Avengers sequel is one of the most talked about and anticipated movies - and it is still two years away. But over the last week or so Whedon has been dropping some hints as to what we can expect from the new film.
He made a surprise appearance at Comic Con to announce that the movie would be called Avengers: Age of Ultron - therefore giving away who was going to be the movie's villain.
Speaking to Total Film the director said: "I was pitching Ultron before I took the job on the first movie.
"I was like, 'I don't know if I want to do this, but for the second one, you should totally do Ultron'. Because he's been a thorn in their side as much as any other character over the years and particularly back in my history.
"He was great. He's somebody who can juice things up and he's a real problem for the Avengers. That's not always easy to find. It's not like the Vulture is really going to give them a hard time for 20 minutes."
Whedon will be back in the director's chair for the film and is currently putting the finishing touches to the script.
Just who will play Ultron is not yet known, but Robert Downey Jr, Chris Evans, Chris Hemsworth, Scarlett Johansson, Jeremy Renner and Mark Ruffalo are all expected to return.
And while the Avengers sequel is still quite a way off there is plenty of Marvel action to keep you entertained before that.
Thor: The Dark World will be released in the Autumn, while Captain America: The Winter Soldier and Guardians of the Galaxy will be released next year.
