Plot hole: In the scene in Hess's office, he agrees to save Sophie's son and remove him from the concentration camp. He also tells Sophie that he'll bring her son to see her the next day. In the very next scene, Sophie attempts to steal Hess's daughter's radio which would completely jeopardize the saving of her son if she was caught. It is unlikely that she would jeopardize the wonderful situation she arranged for her son, by stealing a radio. Later, Hess does not save her son, but Sophie didn't know this would happen, so she would not have attempted to steal the radio at that time.
Sophie's Choice (1982)
1 plot hole
Directed by: Alan J. Pakula
Starring: Meryl Streep, Kevin Kline, Peter MacNicol, Rita Karin
Continuity mistake: There is a long scene wherein Meryl Streep is sitting in a bay window going on about something. When we first see her, her eyes are brown. Moments later, they are blue. At the end of the scene they are brown again.
Stingo: I was twenty two, and a virgin, and was clasping in my arms at last the goddess of my unending fantasies. My lust was inexhaustible. Sophie's lust was both a plunge into carnal oblivion, and a flight from memory and grief. More than that, I now see it was a frantic attempt to beat back death.
Trivia: Meryl Streep could only bring herself to do one take of the choice scene, she begged the movie producers not to make her do it again.
