Glenn Langan (July 8, 1917 – January 26, 1991) was an American character actor on stage and films.
Born in Denver, Colorado, Langan in 1942 appeared on Broadway revival opposite Luise Rainer in J.M. Barrie's Kiss for Cinderella. He made his credited film debut in The Return of Doctor X (1939).
Appeared as a French professor in the romantic Margie (1946), a devoted young doctor protecting Gene Tierney from the evil machinations of Vincent Price in Dragonwyck (1946), and as one of the psychiatrists looking after demented patient Olivia de Havillandin the The Snake Pit (1948). Langan was also gainfully employed in escapist adventure, essaying a square-jawed privateer captain inForever Amber (1947).
Langan's popularity had waned by the early 1950's. He spent the next decade appearing on various television episodes, but eventually achieved a form of cult status as the irradiated 60-foot hero of Bert I. Gordon's often hilarious sci-fi outing, The Amazing Colossal Man(1957). After winding down his screen career in the 1960's, Langan re-invented himself as a successful real estate salesman. He was married for forty years to the actress Adele Jergens.
