Djimon Hounsou out and about in Beverly Hills, California on August 26, 2013.

*Djimon Hounsou has signed on to topline “Air,” a sci fi thriller from “The Walking Dead” creator Robert Kirkman and a member of the AMC show’s ensemble cast, Norman Reedus, The Hollywood Reporter has learned.

The story is set in an underground cryogenic facility after a nuclear fallout renders the atmosphere unbreathable. “Air” centers on its two custodial workers (Reedus, Hounsou), who take care of the cryogenically sleeping personnel that are to re-establish society, but they struggle to preserve their own sanity and lives while maintaining the extremely fragile environment of the last livable place on earth.

The project was previously known as “Wake Cycle” and set up at Boss Media, although the rights lapsed and it went into hibernation mode until Circle of Confusion and Kirkman got involved.

Twice Oscar-nominated actor Hounsou will be seen in the upcoming tentpoles “Guardians of the Galaxy” and “Fast & Furious 7.”
