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.

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.

Anyone who has been following superhero movies knows that Robert Downey, Jr. has signed on to return as Tony Stark in 'The Avengers 2' and 'The Avengers 3,' but his future as Iron Man beyond that is up in the air.

And you get a good look and listen to Ben Kingsley's Mandarin, a taste of Guy Pearce's role in the film, and the sense that this is a film of scale, and that nothing is going to come easy for Robert Downey Jr.'s Tony Stark.

We saw the Avengers on Friday night, and it was absolutely amazing.  It was a really good show, and I'm not even a huge comic book guy.  In case you've lived under a rock, or on Asgard, The Avengers is the best of the Marvel Comics all on the screen at the same time.  I can't wait for a sequel.  One thing I did learn is you'll get dirty looks if you try to crack a joke about the comic book world.
