London (CNN) -- If ever there was a costume that erased gender, it's got to be an astronaut's suit. Big, bulky, with a uniform shape and reflective mask, it's pretty hard to tell whether the person inside is male, female, or Ham the chimpanzee. So when Sandra Bullock plays an astronaut hurtling through space in new blockbuster "Gravity," one of the only clues she's even a woman is the sound of her hysterical gasping: "I can't breathe! I can't breathe!" For 49-year-old Bullock, playing the lead role of Dr Ryan Stone in the thriller which premieres in Britain this week, this is not a female action film -- it's a "human action film."
