Tough big screen leading man Dana Andrews made four visits to “radio’s outstanding theater of thrills,” and the star of Laura, Where the Sidewalk Ends, and The Best Years of Our Lives made memorable impressions as both heroes and villains. We’ll hear him as a writer plotting the perfect murder in “Two Birds With One Stone” (originally aired on CBS on May 17, 1945) and as a cop pursuing a psychotic killer in an adaptation of Ray Bradbury’s “The Crowd” (originally aired on CBS on September 21, 1950).
