Indie thriller adds five more.

Thomas Kretschmann (‘Valkyrie,’ ‘Wanted’), Josie Ho (‘Contagion), Joseph Morgan (‘The Vampire Diaries,’ ‘Immortals’), Erin Richards (‘Breaking In’) and Max Wrottesley (‘Hugo’) are all set to join Sharlto Copley (‘District 9’) on the cast of the indie thriller ‘Open Grave.’

Directed by Gonzalo López-Gallego, ‘Open Grave’ is the “haunting tale of six desperate individuals who wake up with amnesia-like symptoms in a remote, desolate forest next to an open grave of rotting bodies. With nowhere to turn, they are forced to piece together the mysterious, and ultimately horrifying, set of circumstances that brought them together – before it’s too late.”

Filming is scheduled to kick off this week with Atlas Independent’s William Green and Aaron Ginsburg producing with Michael Wunderman.
