Robert Downey, Jr.: 'Guardians of the Galaxy is the best Marvel movie'

Iron Man Robert Downey, Jr. has branded the summer blockbuster Guardians Of The Galaxy the "best Marvel movie ever".

The Marvel Cinematic Universe introduced a new superhero in Peter Quill/Star Lord, played by Chris Pratt, earlier this month (14), and the film quickly become a hit, surpassing the $500 million mark in the global box office.

In a recent interview with the Toronto Sun, Downey, Jr. graciously admits the newest addition to the Marvel family is the one to beat.

He said, "Guardians of the Galaxy, in some ways, is the best Marvel movie ever. It's odd for someone with - on occasion - an ego the size of mine to actually say that...

"It's like you have a great quarterback, and his brother plays for another team, and then you say: 'Look, this is their second cousin and we think he has a great arm and he should start.' And then he goes and wins the Superbowl!"

Ironically, Guardians director James Gunn said at the film's recent press conference in London that he and Pratt have discussed at length what would happen if Downey, Jr. and the rest of The Avengers had a face-off with Quill and his team.

Gunn revealed, "Chris and I were driving somewhere the other day and in the car we were having one of our ridiculous conversations and we were talking about all the different things that could happen to the Guardians in this universe, like we do endlessly, we talk about it constantly.

"And he was saying, 'Dude seriously, I really really think that Star Lord should kill Iron Man. Like it would be so awesome and if he shot him, people would be so surprised".
