EXCLUSIVE: Robert Downey Jr. On Chris Evans Playing Captain America And Who Will Lead 'The Avengers'

Last month, Marvel Studios finished an exhaustive casting search when Chris Evans landed the title role in "The First Avenger: Captain America." While the difficulties of casting the part for two franchises — "Captain America" and "The Avengers" — simultaneously has been previously noted, some observers questioned Evans' casting by raising concerns about his age, his body type and even his seeming lack of knowledge regarding the history of "Captain America."

However, Evans has already received the endorsement of Samuel L. Jackson, one of his co-stars in "The Avengers." During a recent press event for "Iron Man 2," Robert Downey Jr. also weighed in on Evans' new role in the Marvel Cinematic Universe.

"I do know [Evans] and I think it was a very smart casting choice," related Downey. "I know that it was a difficult choice for both the studio to make and for him personally, having been involved in other franchises before. But if I had to venture a guess, I think he'll count himself as lucky and he'll have a good time."

Although Captain America is traditionally the leader of The Avengers, Evans recently expressed his doubt that Cap would lead the team in "The Avengers."

When asked by MTV News if Tony Stark can be led by Evans' Captain America, Downey jokingly replied, "I'll clown all of them. I'll just clown those fools."

Downey also revealed that he believes that "The Avengers" will begin filming next spring.
