Theodore Pellerin, Asjha Cooper, Dale Whibley, Jesse LaTourette, Burkely Duffield and Diego Josef are also on the call sheet for the feature, which is set to begin shooting next week in Vancouver.

An adaptation of the book by Stephanie Perkins, the story sees the graduating class at Osborne High being targeted by a masked assailant intent on exposing the darkest secret of each victim. Only a group of misfit outsiders can stop the killings — before their own secrets are revealed to the world.
