Continuity mistake: The perfect breakfast sandwich is constantly changing. When Sal passes the sandwich to Harley, it's a flat, toasted bread sandwich in plastic cling wrap. When she picks it up off the counter, it's wrapped in tin foil. When she eats it on the street, it's a sandwich with buns wrapped in yellow paper.
Continuity mistake: When Harley has a tray of cocktails in both hands her friends are saying about her cheap looking gold chain...suddenly there's a close up of her holding the chain with one hand, then pans back to her holding the tray of drinks with both hands. (00:05:36 - 00:06:00)
Continuity mistake: The egg sandwich was not sliced, but when Harley opens one end of the wrapper, it has been sliced (with the sliced edge facing outward). When the sandwich flies in the air and lands on the street, there are four pieces of roll, which indicates it was sliced. However, when sandwiches are sliced in half, the half is not turned around like it was when Harley first opened the wrapper and was about to take a bite. (00:13:08 - 00:15:46)
Continuity mistake: In the scene with the sprinklers in the prison Harley gets soaked. She walks into a different room and suddenly she's completely dry.
