With this year’s Sundance Film Festival bringing the newest film from director Ti West, a found footage film he co-directed entitled V/H/S, Deadline has the scoop on who will be joining him for his next project.

The outlet is reporting that Liv Tyler has joined the upcoming project, The Side Effect. The film will follow a woman who becomes part of a pharmaceutical company’s strange experiment that will see her spending several months in space. While there, she somehow becomes pregnant and begins losing her grasp on reality as she tries to figure out how this could happen and how to get out of this astronomical prison she’s stuck in.
