Oscar-winner Edmond O'Brien was one of Hollywood's most colorful character actors, making memorable appearances in The Killers, The Man Who Shot Liberty Valance, Seven Days in May, and more. He brought a tough, hard-boiled intensity to his Suspense appearances: as a reporter on the trail of a story worth killing for in "The Argyle Album" (originally aired on CBS on September 4, 1947) and as a gambler framed for murder in "Muddy Track" (originally aired on CBS on November 11, 1948).
