Body Stealers, The (1969)

aka: Out Of Thin Air

In this obscure British sci-fi flick, a British military paratrooper disappears in mid-air during a jump from an army plane. Two investigators, Bob Megan (Patrick Allen) and Jim Radford (Neil Connery), try to unravel how this happened. What they uncover is an alien plot to steal the bodies of earthlings by snatching them out of the air. Also stars George Sanders and Maurice Evans. Also with Lorna Wilde, Hilary Dwyer, Sally Faulkner, Shelagh Fraser (aka Aunt Beru in Star Wars Episode IV: A New Hope) and Michael Culver (aka Captain Needa, whose apology was “accepted” by Darth Vader in Star Wars Episode V: The Empire Strikes Back).
