Walking Dead creator Robert Kirkman is expanding his horizons of zombies and comic books and moving into the world of film producing, according to The Hollywood Reporter. The veteran comic scribe is set to produce Air, an original sci fi movie, starring Walking Dead’s Norman Reedus and Djimon Hounsou.

The movie will be written by Christian Cantamessa and Chris Pasetto. Cantamessa, who rose to prominence by writing video games such as Red Dead Redemption and Grand Theft Auto: San Andreas, will also make his directorial debut on the low-budget thriller. Here is the description of the plot, according to THR:

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.

Sony Pictures is currently negotiating to acquire the rights to the film.
