Watch: Scarlett Johansson plays an alien in "Under the Skin" teaser

Actress Scarlett Johansson arrives for the screening of "Under the Skin" presented in competition at the 70th Venice Film Festival on Sept. 3, 2013, in Venice, Italy.

As Scarlett Johansson hit the red carpet at the Venice Film Festival on Tuesday to promote "Under the Skin," a teaser for the film has arrived online.

In the film, directed by Jonathan Glazer ("Birth"), Johansson plays a sexy alien on a road-trip through Scotland, seducing and destroying men along her route. Over the course of her journey she begins to gain some sensitivity and human emotion.

Johansson said that to be an alien she had to abandon "these very human instincts that we have, protecting ourselves and wanting to protect one another."

"Under the Skin" is among 20 films competing for the Venice Film Festival's coveted Golden Lion award. The film is also scheduled to screen at the Toronto Film Festival, which begins later this week.
