One of the most exciting pieces of news to come out of San Diego Comic Con this year was the title of the new Avengers movie. Joss Whedon's Age of Ultron will be the follow up to Avengers Assemble, and is due to hit cinema screens in the summer of 2015.

The movie borrows its title from a recent Marvel comic, but that's where it stops, according to Whedon. He's got a whole host of new ideas for old school Avengers villain Ultron, and he's been telling ComicBookMovie.com all about them. For example. Hank Pym (Ant Man) featured in the original Ultron origin story as his creator, but he won't be in the movie. Joss is borrowing bits form various stories to piece together Ultron's rise instead.

'We're crafting our own version of it where his origin comes more directly from The Avengers we already know about" he says. ''It's a little bit darker than the [first] film because Ultron is in the house. There's a science fiction theme that wasn't there in the other one. Nothing can be translated exactly as it was from the comics, particularly Ultron.'' For those of you who have never heard of the character, he's a pretty deadly piece of work.

Ultron aside though, Joss has finally confirmed his plans to bring in brother-sister duo Quicksilver and Scarlet Witch. American Horror Story's Evan Peters is starring as the young lad in X-Men: Days Of Future Past, so we wonder if he'll be the first to bridge the Fox-Disney divide and join Avengers? Meanwhile, reports still suggest that they're eyeing up our Saoirse Ronan for the Scarlet lassie.

If she does get the part, our Saoirse will get to have quite a lot of fun with the character, because Joss has his own vision for the pair. "You know, they had a rough beginning. They're interesting to me because they sort of represent the part of the world that wouldn't necessarily agree with The Avengers", Whedon told IGN. "So they're not there to make things easier. I'm not putting any characters in the movie that will make things easier." Awesome.

Oh, and Hawkeye fans will be pleased to know he gets to do an awful lot more than scowl at the screen in this movie. No complaints from Jeremy Renner this time around so, unless, y'know, they replace him...
