'Avengers' Stars Reveal 'Age Of Ultron' Details

"Avengers: Age of Ultron" is still filming and won't hit theaters until 2015, but Access Hollywood has details on the film's new villain, Ultron!

Access Scott “Movie” Mantz was on the scene at Comic-Con in San Diego where he spoke to the stars about the highly anticipated sequel. Here's some of what they had to say about filming "Age of Ultron" and what Marvel fans should expect in what is bound to be one massive blockbuster:

Robert Downey Jr. on sequel and "Iron Man 4": "['Age of Ultron'] really is gonna deliver!... Let me put it this way, I bet there will be an ['Iron Man 4'} announcement of some sort, sooner than later. You heard it here first!"

Chris Hemsworth on villain Ultron: "[Ultron's] birth happens in the beginning of the film. So he's young on one hand and his artificial intelligence has all the information that has existed and is available in his head, yet isn't quite mature enough to comprehend it in the right way. So he has all sorts of mixed emotions about the Avengers in particular and what they're doing. It's the biggest challenged they've faced yet. The first film is about them creating a team and this is about them being split up in a way and trying to come together and working out where they all stand."

Mark Ruffalo on scope of the sequel and more Hulk: "It's a bigger movie. If you can believe it or not, a more ambitious movie. The Avengers are really up against the ropes in this one. They're up against really formidable foe… there's a lot more Hulk stuff in this… I'm excited by where we're able to go now with the character."

Elizabeth Olsen on making a "scarier" sequel: "It's more ambitious. It adds new elements and almost a scarier threat in a way, [but] it stills has the humor. It still has the fun banter between the characters, but there is this darker deeper fear that is rooted and you really get inside everyone."

Access also found out what Chris thought about Thor's gender change in the comic books: "I think it's great. There's too much testosterone in the superhero world, so why not?"

"Avengers: Age of Ultron" hits theaters on May 1, 2015.
