Doom/Serenity 2 Film Boxset (DVD)

Serenity 
Captain Malcolm Reynolds, a hardened veteran (on the losing side) of a galactic civil war, now ekes out a living abroad his ship, Serenity. He leads a small, eclectic crew, but when Mal takes on two new passengers - a young doctor and his telepathic sister - he gets much more than he 
bargained for. From the award winning directors and writers of Buffy the Vampire Slayer.

DOOM 
Something has gone wrong at a remote scientific research station on Mars. All research has ceased. Communication has failed. And the messages that do get through are less than comforting. It's a level 5 quarantine, and the only souls allowed in or out are the Rapid Response Tactical Squad, a squadron armed to the teeth with unprecedented firepower to carry on their mission: nothing gets out alive. But a legion of nightmarish creatures of unknown origin lurks behind every wall and stalks the countless rooms and 
tunnels? far more powerful and blood-thirsty than anyone could ever imagine. Doom brings you all the visceral excitement and startling action that made its game predecessor a global phenomenon.
