Liv Tyler is set to star in psychological thriller The Side Effect.
The Lord Of The Rings actress is said to be portraying Catherine Rigby, a woman who spends several months alone in space as an experimental subject for a global pharmaceutical company, and finds herself inexplicably pregnant.
"The role of Rigby is a fantastic character within a great thriller and I am looking forward to sinking my teeth into the part," she told Deadline.
Liv, who previously starred in thriller The Strangers, said she was excited about working with writer-director Ti West: "He's a super-talented exciting young filmmaker."
Ti added: "It was essential that I find an actress who could portray a wide range of emotion and always earn the audience's sympathy no matter what the situation. As soon as I sat down with Liv, it was obvious she was the one."
The 34-year-old actress was last seen in superhero comedy caper Super alongside Ellen Page and Kevin Bacon, and will show her new film Robot And Frank at the forthcoming Sundance film festival.
