Born in London, Les Tremayne moved to America in his early teens. Educated at Northwestern, Columbia and UCLA, Tremayne went on the stage in the early 1930s, where his distinguished demeanor and mellifluous voice served him well. He rose to stardom on radio, appearing in literally thousands of "Golden Age" broadcasts, notably as star of the long-running anthology The First Nighter Program. In films from 1951, Tremayne brought a large dose of sober credibility to many an otherwise hard-to-swallow science fiction opus. At his best as General Mann in War of the Worlds (1953)--the General's explanation of the Martian's invasion strategy remains one of the finest pieces of pure exposition in all of "fantastic" cinema--Tremayne was also successful in maintaining his dignity in cheapies of the Angry Red Planet (1959) and Slime People (1965) variety. The actor's contributions to the sci-fi genre were hosannahed in the direct-to-video production The Attack of the B-Movie Monsters (1985). In addition, Tremayne showed up in several non-genre efforts, usually in small but substantial roles like the auctioneer in North by Northwest (Tremayne's single scene in this 1959 Hitchcock classic also featured his old First Nighter colleague Olan Soule). Busiest on television as a commercial spokesman and voiceover artist, Tremayne found time to appear on the prime-time TV version of radio's One Man's Family (1951); as Inspector Richard Queen on the 1958-59 incarnation of the venerable Ellery Queen; and as Mentor on the Saturday morning Captain Marvel-inspired weekly Shazam! (1974-77). In 1995, Les Tremayne, as golden-throated as ever, was inducted into the Radio Hall of Fame during a moving, nationally broadcast ceremony from Chicago's Museum of Broadcasting.
