VENICE, Veneto - US star Scarlett Johansson spooked the Venice film festival Tuesday with her performance as an alien in human form who hunts men, seduces and feeds on them.
"Under the Skin", by British director Jonathan Glazer, plays with light and polished dark surfaces to evoke a sleek alien environment, which is juxtaposed with shots of Glasgow streets and the Scottish highlands.
Johansson's character Laura observes humans with a clinical interest, devoid of impulses such as self-preservation or the emotional drive to save others - as shown in one chilling scene where she leaves a toddler to drown as she stalks her male prey.
Slowly, she begins to comprehend human feelings and explore her sexuality beyond the drive to feed, tentatively forming her first relationship - only to discover that the hunter has become the hunted.
The film eludes the science-fiction label, feeling more like a blend of gritty documentary and thriller, flirting with horror without the gore.
"We wanted to make a film about looking at the world through an alien eye. It's about how Laura feels," said Glazer, who based the screenplay on Michel Faber's 2000 novel of the same name.
Johansson said she found it difficult at first to get into her character.
"It became very clear early on, after about three or four takes, that any ideas I had about how to go about playing the character were completely irrelevant. It took a couple of weeks to find our footing," she said.
