- Joe's narration for the scene of him paging through Norma's script:
Sometimes it's interesting to see just how bad bad writing can be. This promised to go the limit.
- Joe's expression of disbelief in astrology, when Norma claims the stars foretell Cecil B. DeMille greenlighting her return:
Norma: Here's the chart from my astrologer. She read DeMille's horoscope. She read mine.
Joe: She read the script?
- Norma's Charlie Chaplin impression is actually amusing. At least until Max interrupts.
- A grim joke during the final scene, but the police are unable to use the phones because gossip columnist Hedda Hopper is calling in her report.
