On the train to Philadelphia, Al (John Garfield) talks to Lee (Dane Clark) about the difficulty he anticipates in getting a job for a blind man. Lee responds that because he, Lee, is Jewish, he has trouble finding a job as well and then waxes philosophic about a day when people are discriminated against for any reason. But in real life, it was Garfield who was Jewish.
