Newbie screenwriters Brandon Bestenheider and Allen Bey have sold their spec script Grim Night to Universal Pictures for a reported six-or-seven figure sum. Director Bryan Bertino’s (The Strangers) production shingle Unbroken Pictures is attached to produce. No word yet on whether Bertino will direct the project as well.

Grim Night follows an American family as they attempt to survive an attack by creatures who emerge once a year to murder thousands of people around the world. A teaser for the spec depicts the monsters as Grim Reapers—hooded robes and all. But, unless cutbacks have forced the Reapers to work one day a year, I’m pretty sure they’re busy year round. Therefore, these Grims must be a whole new kind of evil.
