Relativity Media – who now has its own distribution arm after acquiring the marketing and distribution operations of Overture Films earlier this year – has snapped up domestic rights to Shark Night 3D from Sierra Pictures and partner Incentive Filmed Entertainment. Relativity announced Tuesday that it will release the shark pic next year and will announce a new title and a specific release date shortly. The David R. Ellis-directed pic stars Sara Paxton, Dustin Milligan, Katharine McPhee, Chris Carmack, Alyssa Diaz, Joel David Moore, Donal Logue, Sinqua Walls and Chris Zylka. The story, penned by Jesse Studenberg and Will Hayes, surrounds a group of college friends spending a weekend at a house on the lake, only to find a shark lurking. Relativity is also releasing Season of the Witch next year.
