'Avengers' Cast: Moscow Premiere!

Jeremy Renner, Roberty Downey Jr., and Scarlett Johansson premiere The Avengers on Tuesday (April 17) at Oktyabr Cinema in Moscow, Russia.

Co-stars Chris Hemsworth, Tom Hiddleston, and Mark Ruffalo also joined them on the red carpet after promoting the action flick at a photo call earlier in the day.

“None of [our costumes] were comfortable, especially in the middle of the dessert,” Chris recently told Nightline (via ABC News). “We all had [a little air-conditioning unit] option. It was like this T-shirt you’d wear with like a hose that you’d plug in and there was cool water.”

FYI: Scarlett is wearing a Nina Ricci dress with Giuseppe Zanotti heels, a J/Hadley ring and a Karma El Kahlil cuff.
