Curmudgeon Films has picked up screen rights to the story of Bob Lazar, a man who claims to have worked at S4, a secret military base near Area 51, where he examined an alien spacecraft recovered by the U.S. military, according to The Hollywood Reporter.

Lazar left the project in 1989 and recounted his story to Las Vegas reporter George Knapp.

A screenplay tentatively titled S4: The Incredible True Story of Bob Lazar, is being written by Kenneth Yakkel.
