SCARLETT JOHANSSON could dress up as a monster and still look sexy. So it comes as no surprise to hear the actress has landed the role of an alien seductress in a new flick called Under the Skin. RYAN REYNOLD`S missus will play Isserley, an extra-terrestrial sent to Earth who captures and eats men. I`m quietly scared and excited. A spokesman for production company Film Nation tells the Hollywood Reporter: "Johansson plays an alien on earth, disguised as the perfect aesthetic form of a mesmerising woman. "She scours remote highways and desolate scenery looking to use her greatest weapon to snare human prey - her voracious sexuality... Taking her point of view throughout, the film presents a unique look at our world through alien eyes." Film Nation boss Glen Basner adds, "We`re so excited to be working on this arrestingly original movie. "How could we pass up the chance to work with a visionary director like Jonathan, especially when combined with the intriguing notion of Scarlett Johansson as a ruthless alien seductress?" Production on the project - which has been adapted for the big screen by Walter Campbell - is set to begin in spring 2011. Sexy Scarlett already has one villain role under her belt - playing Natasha Romanoff in Iron Man 2.
