Robert Downey Jr

Well that certainly escalated quickly: over the last couple of weeks Robert Downey Jr. has played rather coy about what's next for Tony Stark and Iron Man in the Marvel Cinematic Universe, but now it looks like we know the answer, as he's just been recruited for 'Captain America 3,' in a storyline that's said to bring Marvel's Civil War arc to the big screen -- which is a rather huge development.

There's been a lot of 'Iron Man 4' talk over the past few days as Robert Downey, Jr. continues his whirlwind promotional tour for 'The Judge' across a multitude of talk shows. He's confirmed it, issued demands, backpedaled, confirmed it again and now, via an appearance on David Letterman last night, he clarified all the recent rumors and (we think?) issued the definitive word on 'Iron Man 4' and his future at Marvel.

Marvel Studios and the character of Tony Stark/Iron Man transformed Robert Downey Jr. from a has-been into one of the biggest movie stars on the planet, so it's not surprising that he'll sing their praises outside the context of the movies he stars in. However, he recently took it a big step further, declaring 'Guardians of the Galaxy' to be the best Marvel movie yet. Yep, even the ones that he's not in.

It's inevitable: one day there will be an 'Avengers' reboot. It's hard to think of now, as 'Avengers 2' hasn't even hit theaters and Phase 3 of Marvel's Cinematic Universe hasn't even begun yet. But, once Robert Downey, Jr., Scarlett Johansson, Chris Hemsworth, Mark Ruffalo, Chris Evans and Jeremy Renner all play through their contracts, Marvel is going to have to start over. Now, we don't think Marvel would ever reboot 'The Avengers' as a 70s detective TV series, but if they did? It'd look a lot like this...

By now, everyone is familiar with the ALS Ice Bucket Challenge, where people heed the call to throw buckets of ice water on themselves to spread awareness of ALS and raise donations to support The ALS Association. Everyone, from your many Facebook friends to A-list celebs have been participating, but, for us, there's nothing like seeing the likes of Thor, Iron Man and Star-Lord step up to the plate.

We've known for a little while that Marvel is taking a break from 'Iron Man' after three films with star Robert Downey Jr. And while they will likely make another 'Iron Man' in the future, it hasn't been clear if Downey Jr. would don the suit again. In a new interview, the actor and star of 'Avengers: Age of Ultron' hints that he's not quite ready to give it up.

On the heels of the reveal of the exclusive concept art poster for 'Ant-Man,' Marvel Studios has also unleashed two concept art posters for 'Avengers: Age of Ultron' at Comic-Con 2014, featuring our heroes battling a whole bunch of nasty robots.

Robert Downey Jr. may be relatively new to Twitter, but he's taken to it like a duck to water as he's made fans happy by tweeting a photo from the set of 'The Avengers 2.' Downey has a penchant for charming self promotion that would put even Tony Stark to shame.

We'd probably be upset too, if somebody told us we were going to meet Iron Man, and we actually met Robert Downey, Jr. in a polo shirt ... if we were 18 months old, which is why this kid is crying.
