I remember this film being listed in TV Guide as a 1958 title, but it's a 1969 Tigon picture toplining George Sanders in one of his last roles. A featherweight science fiction story that unravels as more of a dreary espionage tale, as military parachutists disappear in midair, with square jawed Patrick Allen (ISLAND OF THE BURNING DOOMED) on the case when not engaged in serious female seductions (like Siamese twins joined at the mouth). Aliens are responsible but it doesn't really add up to much. Sanders has a good deal of screen time as the General, but little to do, while second billed Maurice Evans is even less lucky. Hilary Dwyer (CONQUEROR WORM, THE OBLONG BOX, CRY OF THE BANSHEE) plays a dedicated scientist who can't resist Allen's advances for long, Robert Flemyng (THE HORRIBLE DR. HICHCOCK, THE BLOOD BEAST TERROR) is another military man, and Neil Connery (Sean's brother) makes his second and last screen appearance, following the Italian James Bond satire OPERATION KID BROTHER, featuring Bernard Lee, Lois Maxwell, Adolfo Celi, and Daniela Bianchi. On television, THE BODY STEALERS was retitled THIN AIR.
