Scarlett Johansson hit the Glasgow, Scotland, set of Under the Skin earlier today with a new look. Scarlett is wearing a dark wig for the movie, in which she plays an alien who seduces men living in the Scottish Highlands. Good looks may have won Scarlett this part, but her sexiness is reportedly the reason she lost the role of Lisbeth Salander in The Girl With the Dragon Tattoo to up-and-comer Rooney Mara. In a recent interview with Vogue, director David Fincher explained his decision. He said he picked Rooney because, "The thing with Scarlett is, you can’t wait for her to take her clothes off." Scarlett nails the role of a sexy badass in the first Avengers trailer as her character, Black Widow, joins forces with Chris Hemsworth, Jeremy Renner, and Robert Downey Jr.'s Marvels superheroes.
