The 32-year-old actress, who plays alien-battling archaeologist Dr Elizabeth Shaw in Ridley Scott's highly-anticipated movie, said she begged her make-up artist to apply extra blood and sweat, reported Contactmusic.
"I am running around half naked in a couple of scenes and I never thought about it. Ridley (Scott, director) didn't want me dressed that way for kicks. It is not sexy, just very basic and it serves the scene.
"I am not here to be sexy. Sometimes you can do a sexy part or play a woman who is supposed to be beautiful and then we can do beauty. That is for another movie. But for this movie it was sweat. More sweat, then more dirt. More blood. The makeup artist said it was unusual to ask for more fake blood and sweat, but I loved it," she said.
