Character mistake: When Tommy walks into the flower shop, he tells the clerk that his sister is getting married. For the purpose of their mission, Sally, the sister in question, is actually supposed to be Tommy's aunt. (00:05:20)
Other mistake: When Dick is trying to get into the jewelry store, the clerk keeps trying to buzz him in. When that doesn't work because Dick doesn't understand to wait for the buzzer to finish before he tries opening the door, the clerk goes over to the door and unlocks the deadbolt and opens the door for him. If the door was locked by a deadbolt, then a buzzer wouldn't really do anything to unlock the door. (00:14:05 - 00:15:00)
Suggested correction: It's not a deadbolt. If it was they have retracting deadbolts.
