Johansson chatted on The Tonight Show with Jay Leno Wednesday about her fan-favorite catsuit costume. "It's sort of like a wetsuit I suppose," Johansson, 27, explained to Jay Leno."It's like a little adult ones."
Leno was very intrigued and asked, "Does it breathe? Are you sweating in this thing?"
The actress also talked about her recent trip to Russia to promote the film with her hunky male costars -- Chris Hemsworth, Chris Evans, Robert Downey Jr. and Jeremy Renner, to name a few.
“My castmates are just beasts. They are obviously big, whirly, hunking dudes. They just kind of like to mop the floor with my remains," she joked. "So we went out, and everyone was really into the Russian standard vodka, which is apparently the thing. I actually don’t even remember the rest of the trip.”
