Factual error: Bessie says she was going to study veterinary medicine at Texas A and M. That would have been approximately 1940. Neither women nor people of colour were admitted to TAMU until 1963 so she could not have even been able to apply.
Continuity mistake: When the boys are playing at Norman's father's apartment, we see a ball hit a lamp to the left of the sofa, denting the lampshade. We see the lamp fall and hear it shatter. Later we see the intact lamp back on the table.
