EXCLUSIVE: Relativity has acquired Sam & Liz: A Killer Love Story, an action sci-fi spec script by Feed The Devil scribe Matt Altman. Jon Shestack and Jim Wedaa are aboard to produce.

The logline: Sam is an average guy working a 9 to 5 job that he hates, wishing for a more exciting life. When he meets gorgeous thrill-seeker Liz, he gets more more than he bargained for. Together they go on a wild ride discovering that nothing they know about themselves is true and their connection to each other has surprising and deadly consequences.

Relativity’s Richard Potter and Daniel Herther will oversee. Altman is repped by APA, Parallax Talent Management and Stone, Meyer, Genow, Smelkinson & Binder.

Shestack’s producing Carter Beats The Devil at Warner Bros. with Phil Lord and Christopher Miller developing. Relativity just opened The Woman In Black 2: Angel Of Death and releases Black Or White January 30.
