EXCLUSIVE: Screen Gems will co-finance with Spyglass and distribute The Vow, the Michael Sucsy-directed film that will star Rachel McAdams and Channing Tatum. The film is based on a true story of a newly married couple whose car is rear-ended by a truck. She loses all recent memory-including that she’s married–and they struggle together to gain it back. Spyglass put together the project, and Sucsy, who directed HBO’s Grey Gardens, is rewriting. This puts Clint Culpepper’s Screen Gems back in the Channing Tatum biz, after the Sony-based shingle distributed another romantic weeper, Dear John. Spyglass’ Roger Birnbaum, Gary Barber and Jonathan Glickman are producing. Shooting starts September in Toronto.
