Stage star, screen actor, and train imitator - no, really - Reginald Gardiner was an in-demand comedy star in the 1940s. He appeared alongside Charlie Chaplin and Barbara Stanwyck, and he memorably impersonated train engines for a royal audience at Buckingham Palace. We'll hear him in a murder mystery on an ocean liner with Olivia de Havilland in "Voyage Through Darkness" (originally aired on CBS on September 7, 1944). Then, he's haunted by music and plagued by deadly delusions of grandeur in "The Merry Widower" (originally aired on CBS on October 12, 1944). Plus, Gardiner plays a debonair detective in the audition recording for the comedy-mystery The Gentleman.
