Jonathan Glazer's " Under the Skin " is one of the most haunting, bizarre and disorienting films likely to arrive in theaters this year. It also features a very familiar face in disguise. Scarlett Johansson is a highly recognizable actress in normal circumstances, but take her to Scotland and put her in a short black '70s-esque wig, and you've got a completely different woman. In her best performance yet, Johansson transforms as Laura, an alien seductress who hunts single, wandering men. Since "Under the Skin" was shot mostly guerilla-style with non-actors sometimes unknowingly taking part in the film, Johansson had to improvise her conversations with random Scottish passersby while trying to not give away her real identity as a Hollywood star. Yet beyond the film's fascinating production and Johansson's impressive performance, "Under the Skin" also marks the actress' first fully nude role. In the film, Laura lures men into her shadowy lair with her perceived innocence, then traps them with one powerful weapon: her naked body. At a press conference for the film in New York last month, Johansson discussed how she heavily considered the nudity of the part to make sure it was significant to her character's journey.
