After the war, Garfield starred in a series of successful films such as The Postman Always Rings Twice (1946) with Lana Turner, Humoresque (1946) with Joan Crawford, and the Oscar-winning Best Picture Gentleman's Agreement (1947). In Gentleman's Agreement, Garfield took a featured, but supporting, part because he believed deeply in the film's exposé of antisemitism in America. In 1948, he was nominated for the Academy Award for Best Actor for his starring role in Body and Soul (1947). That same year, Garfield returned to Broadway in the play Skipper Next to God. Strong-willed and often verbally combative, Garfield did not hesitate to venture out on his own when the opportunity arose. In 1946, when his contract with Warner Bros. expired, Garfield decided not to renew it and opted to start his own independent production company, one of the first Hollywood stars to take this step.
