Rachel McAdams and Channing Tatum have signed on to star in The Vow for Spyglass Entertainment.

According to Variety, Michael Sucsy, director of Grey Gardens, is directing the project and is also re-writing the script.

The project is based on a true story about a young woman who loses all recent memory in a car accident and struggles to rebuild her identity.

The story of the couple -- Kim and Krickitt Carpenter -- dates from 1993, two months after their marriage, when their car was hit from behind by a truck.

Production is set to start at the end of August in Chicago and Toronto.
