Mirror, mirror on the wall, who's the creepiest one of all? Relativity hopes its upcoming film Oculus will rank pretty high on that list.

Directed by Mike Flanagan, who also helmed the 2011 fright flick Absentia, Oculus finds Kaylie (Karen Gillan) reuniting with her brother Tim (Brenton Thwaites), who recently got out of a mental hospital. Kaylie is convinced a childhood tragedy was actually caused by a strange mirror in the house, and while investigating, the pair experience flashbacks featuring Katee Sackhoff as their mom. But can they be believed?

Oculus lands in theaters on April 11.
