“Dr. Who” starlet Karen Gillan is the first actor cast in Film District and Intrepid Pictures’ new supernatural thriller Oculus. The film is directed by Mike Flanagan (Absentia), from a script by Flanagan and Jeff Howard, and is slated to go into production in the Fall.

Oculus follows a twenty-something brother and sister (Gillan) duo orphaned as children after the mysterious murder of their parents, of which the brother is charged with by authorities. His sister, however, continues to believe that a haunted antique mirror is truly responsible for their deaths.

Gillan is best known for her role as Amy Pond on Britain’s long-running sci-fi series “Dr. Who.” The Scottish actress and former model can also be seen in Vertigo Films’ creature-feature Outcast.
