Scarlett Johansson felt “so sorry” for the stuntmen in her upcoming movie Iron Man 2 — because they couldn’t go to the toilet! The actress — who wears a skin-tight catsuit in the flick for her role as the Black Widow — says her colleagues could rarely relieve themselves because of their heavy and complicated costumes. “You’re working with the stunt crew and they’re going through the craziest stuff so you feel bad about complaining that your knee has been blue for three months,” explains Scarlett. “The guys doing the stunts in those Iron Man suits, they can’t move in it and can’t take it off. “I’d say, ‘Have you peed today?’ and they’re like, ‘No, we can’t move, we can’t take it off, we can’t drink any water.’ I felt so sorry for them.”
