Audio problem: When Joan is scrubbing the floor in the foyer, the sound doesn't match the scrubbing. Joan picks the scrubbing brush off the floor, yet we still hear the scrubbing of the floor with the scrub brush in the air. (00:05:28)
Other mistake: When Joan is cutting up her rose garden, she is ranting and raving about how mad she is at Mayer, and how they're calling her box office poison. But if you look closely at her lips, they aren't moving.
Joan Crawford: Tina! Bring me the axe!
Trivia: Faye Dunaway plays Diana Scarwid's mother in the movie, even though in real life she's only 14 years older than Scarwid.
