Continuity mistake: When the main characters visit Montreal and with their friends they go out to eat at a diner and he creates a "home" out of 4 toothpicks, 3 sugar cubes and a coaster. As the camera goes back and forth in the conversation, watch the "home" on his plate of pancakes. It falls and appears to be scraped and turned in a different direction on his plate by the end of the conversation.
Continuity mistake: An overhead shot shows Olivia squirting ketchup onto a pancake, nearly covering it. In the following shot, the amount of ketchup on the pancake has decreased.
Continuity mistake: During the scene when Notorious B.I.G. is in the hotel room talking to Faith Evans on the phone, you can see a silhouette of a woman in the background. Several times in a row when the scene cuts back to Notorious, the silhouette is shown making the same movement of walking forward and sitting on the edge of the bed.
