Scarlett Johansson is no stranger to playing a seductress, but she's about to take her sex appeal to an out-of-this-world level (literally). The actress will play an alien in Under the Skin, a sci-fi flick about an extraterrestrial disguised as a human. She patrols desolate areas of the earth, using her looks to prey upon innocent humans. Johansson is hardly the first woman to play a sexy alien (has anyone seen My Stepmother Is an Alien or Species?), so I'm hoping there's more to this story than just watching her play the damsel in distress before eating men for breakfast.
