Under the Skin is a 2013 science fiction film directed by Jonathan Glazer and written by Glazer and Walter Campbell, based on the 2000 novel by Michel Faber. It stars Scarlett Johansson as an extraterrestrial disguised as a human who preys on lone men in the evening hours in Scotland. Glazer developed Under the Skin for over a decade. He and Campbell pared it back from an elaborate, effects-heavy concept to a sparse story focusing on an alien perspective of the human condition.
