Yes, actor Shalto Copley (District 9, Elysium) does have an acting career outside of the films he makes with Neill Blomkamp. This is an intense trailer for a new thriller that he stars in called Open Grave.
The story centers on a man (Copley), who "wakes up in a pit of dead bodies with no memory of who he is or how he got there. Fleeing the scene, he breaks into a nearby house and is met at gunpoint by a group of terrified strangers, all suffering from memory loss. Suspicion gives way to violence as the group starts to piece together clues about their identities, but when they uncover a threat that's more vicious—and hungry—than each other, they are forced to figure out what brought them all together—before it's too late."
The movie looks like it will be a really good dark thriller, and it's set to be released on VOD on December 24th, and then get a theatrical release on January 3rd.
