When Angel is dropped off in front of Mann's Chinese Theatre, the movie marquee reveals that Star Wars: Episode VI - Return of the Jedi (1983) is playing.
In any distant shots where Angel is running, she is wearing thick, chunky high heels, as opposed to the stilettos she is wearing in closer, alternate shots when merely walking or standing.
During the final chase scene Molly/Angel is using a large caliber, long barreled revolver which should chamber a maximum of six shots. She fires six times during the chase. Then the gun is taken away from her a fired a seventh time. There is no indication Molly was carrying extra rounds, or stopped to reload if she had.
When Angel is studying in the hotel lobby you see a hotel employee putting two chairs upside down on top of a table as he starts to clean up for the night, in the next shot he repeats and starts with the same two chairs again.
