Robert Downey Jr. and Mel Gibson first worked together twenty-four years ago in the 1990 film 'Air America' and have maintained a friendship ever since. Which may be why there's a rumor that Downey Jr. is trying to pull strings and get both Gibson and Jodie Foster into the Marvel universe, and possibly into 'The Avengers: Age of Ultron.'

'The Avengers 2,' officially titled 'The Avengers: Age of Ultron,' will see a few new faces joining the ranks of the Marvel Cinematic Universe -- Quicksilver, Scarlet Witch and, of course, Ultron himself. But is Marvel Studios planning on adding another more secretive baddie to liven things up other than the near indestructible super robot?

We knew that the original team of Avengers would return for 'Avengers 2' plus the new additions of Quicksilver and Scarlet Witch. But, now we've learned that another character from the Marvel universe will make an appearance in the upcoming sequel. Don Cheadle will join the 'Avengers 2' cast, bringing Colonel James Rhodes/War Machine to the fight against Ultron.

Just the other day, we learned that 'The Avengers 2' was officially adding Elizabeth Olsen to the cast as Scarlet Witch. Now what about her brother? Well, after months of teasing his involvement, it looks like Olsen's 'Godzilla' co-star, Aaron Johnson, is officially on board as well, playing her on-screen sibling Quicksilver.

When James Spader was officially cast as Ultron in 'Avengers 2,' Marvel announced the occasion in grand style on their own style.

'The Avengers 2' teaser debuted at the 2013 Comic-Con in grand fashion. At the very end of Marvel's panel, an unannounced Joss Whedon came on stage to show a brief video.

The crowd went nuts. But, if you weren

Joss Whedon's 'The Avengers 2,' titled 'Age of Ultron,' is the most-anticipated film of summer 2015 -- aside from Zack Snyder's 'Batman vs. Superman,' of course. Production on the sequel is set to kick off in 2014, and you could be there in person to witness the action firsthand.

'The Avengers 2,' titled 'Age of Ultron,' will see Marvel's superhero gang do battle against (as the title suggests) the comic-book villain Ultron, but one character of the Marvel Cinematic Universe who will likely sit this one out is Iron Man's squeeze, Pepper Potts.

Chris Hemsworth is a busy man. In addition to being the Marvel movie universe's Thor, the Australian actor has been promoting the upcoming Ron Howard drama 'Rush,' which sees him stepping into the role of Formula One racer James Hunt.

'Avengers' director and current Marvel Studios creative head muckity-muck Joss Whedon has a knack for killing off beloved characters. You need to look to further than 'Buffy,' Firefly,' 'Angel' and, of course, 'The Avengers' for evidence. But, as he prepares to shoot 'Avengers 2: Age of Ultron' in a few months, will Whedon take things up a notch and, gulp, kill one of the Avengers? "Maybe...

Ever since the title 'The Avengers: Age of Ultron' was revealed by Marvel and Joss Whedon at Comic-Con 2013 last month, there's been a lot of talk of how this epic villain will be handled for his big-screen translation. Now it seems we've gotten some (vague) answers from Whedon himself, who opened up about the difference between comic book Ultron and movie Ultron.

Even though 'The Avengers: Age of Ultron' won't hit screens until 2015, the casting process is under way and Joss Whedon is looking for his Wanda Maximoff -- also known as The Scarlet Witch -- for the upcoming movie. Previously Saoirse Ronan was the top contender, but it appears she's passed and that the part may have been offered to Elizabeth Olsen.
