Remember, The Avengers is a team movie — and there’s no “I” in team.
There is, however, an “I” in Iron Man, and since we probably wouldn’t have this movie if it weren’t for the charisma that Robert Downey Jr. brought to the original 2008 movie, it’s fitting that Downey lands at center stage in the new poster.
Here we zoom in for a close-up, but the full poster (which you can see at the end of this gallery) shows off Tony Stark’s new look, which Marvel Studios chief Kevin Feige confirms will be “a gadget-laden” Mark 7 suit.
“I’m still trying to, without moving backwards, remember the character that [Iron Man and Iron Man 2 director] Jon Favreau and I created, and be true to that,” Downey tells EW.
It’s also important to be true to the original Marvel Comics history, but Downey acknowledges that they’ve had to streamline their vision over the years as the possibility of this movie loomed.
“Avengers has always been this kind of hovering [thing]. Is it really possible? I just think that it was an incredibly ambitious notion, and looking back at Marvel and their fledgling years, they always had a vision of this … although not entirely accurately.”
Downey laughs: “In one teaser I say, ‘I’m putting a team together,’ and in the other one I’m like, ‘What do you mean I can’t join the team?’ But aside from that, it kind of really tracks through.”
