Scarlett Johansson will star as a woman who is not of this Earth in the new sci-fi alien project Under the Skin, according to Heat Vision Blog. Here's a description of Scarlett Johansson's alien character in the project:

"Johansson plays an alien on earth, disguised as the perfect aesthetic form of a mesmerizing woman. She scours remote highways and desolate scenery looking to use her greatest weapon to snare human prey -- her voracious sexuality. She is deadly efficient, but over time becomes drawn to and changed by the complexity of life on earth. With this new found humanity and weakening alien resolve, she finds herself on a collision course with her own kind. Taking her point of view throughout, the film presents a unique look at our world through alien eyes."

Sexy Beast director Jonathan Glazer co-wrote the script with Walter Campbell which he will direct from. The script was based on the novel by Michael Faber.

Nick Wechsler and James Wilson will produce the movie for FilmNation, with production set to start in the spring of 2011.
