Factual error: When Sue Ellen is shown commuting on the 405 freeway during heavy traffic, she is heading to work, indicating morning - yet the angle of the sun and shadows show it is late afternoon.
Continuity mistake: In the scene where Sue-Ellen has just come home from work, she places her pocketbook on the kitchen island. In the next scene the secretary is going through Sue-Ellen's office and finds her pocketbook and goes through it. How can that be if Sue-Ellen brought it home with her? (01:17:15 - 01:19:35)
