Continuity mistake: I don't think it's quite a mistake, but in almost every scene with Madonna, she has a mysterious shadow over her forehead. In full shots, no shadow, but when they cut to her close-up, there it is. It's more annoying than anything else (aside from her acting).

Continuity mistake: When Monica gets out of her car after her first day at the bank, she stumbles over her shoes. She takes them off, talks to Q for awhile, and then heads into the house. Watch as she rounds the corner to the house (right when she gets to the hedges, watch carefully because she walks around the hedges fast) you can clearly see that she does in fact have her shoes on, without her putting them back on. She didn't even bend down like she should if she were putting them back on.
