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.
Continuity mistake: When Dustin Hoffman (dressed as Dorothy) goes to babysit for Jessica Lange he takes a bunch of flowers as a present. Jessica Lange takes them from him and throws them on the kitchen table. Then she walks into the kitchen (shot from different angle) still holding the flowers and throws them on the table (again).
