Writer-director Ti West (The Innkeepers) has found the star of his next project. Deadline reports that Liv Tyler will star in the psychological sci-fi thriller The Side Effect. The horror story centers on “a woman who spends several months alone in space as an experimental subject for a global pharmaceutical company, and finds herself inexplicably pregnant.” So it’s kind of like Moon, but with the added terrors of ghost reproduction. Though the film is still in the horror genre, West insists that it’s fairly different from his previous films as it focuses more on the psychological.

I’d expect a title change on The Side Effect, as Steven Soderbergh is gearing up to shoot a film called The Side Effects. West will be at Sundance next week to debut the found-footage horror film V/H/S which he co-directed. If you’re unfamiliar, his earlier works include The House of the Devil and Cabin Fever 2: Spring Fever. Tyler will also be in attendance at Sundance with her latest effort Robot and Frank.
