Berry Kroeger (pronounced "Kroger", not "Kreeger") got his start in network radio, where his velvety voice was heard announcing several major dramatic anthologies; he also played a variety of leading radio roles, including the heroic soldier-of-fortune The Falcon. While appearing on Broadway in Saint Joan, Kroeger was discovered by filmmaker William Wellman, who cast the actor in The Iron Curtain. This 1948 Cold-War film represented the first of many unsympathetic movie assignments for Kroeger, ranging from the smarmy Packett in director Joseph L. Lewis' Gun Crazy (1949) to the mad-scientist mentor of Bruce Dern in The Incredible Two Headed Transplant (1971). Kroeger's marked resemblance to Sydney Greenstreet served him well when he essayed a Greenstreet take-off in "Maxwell Smart, Private Eye," an Emmy-winning episode of TV's Get Smart. Most of Barry Kroeger's film characters can be summed up in a single word: slime.
