"Pretty Little Liars" star Shay Mitchell to toplie "Cadaver" thriller

- Pretty Little Liars star Shay Mitchell will star in Cadaver, a horror thriller from Screen Gems, The Hollywood Reporter said.

It is a noteworthy move for Mitchell, who has starred on the hit TV show for seven seasons. The Canadian actress just made her feature debut with April’s all-star comedy Mother’s Day but with Cadaver, she now jumps to headliner status.

Diederik Van Rooijen is directing the project, which is being produced by Sean Robins and Todd Garner via their Broken Road Productions banner.

Written by Brian Sieve, Cadaver centers on a disgraced ex-cop and recovering addict who takes a job in a graveyard shift at the morgue of the hospital in which she got sober. Soon after a mysterious and brutally massacred body is delivered to the morgue, the woman begins to witness terrorizing and violent murders, leading her to face off against an evil entity.

Screen Gems’ Michael Bitar brought the project into the studio. President Clint Culpepper and executive vp Scott Strauss will both oversee the film for the company.
