Dennis Quaid, Tyrese Gibson, Jon Tenney are finalizing deals to join the Screen Gems thriller "Legion" reports Variety.

The trio join the already cast Paul Bettany, Charles S. Dutton, Lucas Black, Kate Walsh, Adrianne Palicki, Kevin Durand and Willa Holland.

Scripted by Stewart and Peter Schink, the thriller casts Bettany as the archangel Michael, the only one standing between mankind and an apocalypse, after God loses faith in humanity.

Man's lone hope rests with a group of strangers who must deliver a baby they realize is Christ in his second coming.

Scott Stewart makes his directorial debut on the project which is about to get under way in New Mexico.
