Trivia: Johnny Depp was allegedly excited about the role of Edward Scissorhands. He was annoyed by the "teen idol" image that he was getting from the show "21 Jump Street" and wanted to do something very different.
Trivia: Tom Hanks and Jim Carrey were both considered for the role of Edward. According to Johnny Depp, there was a day when two girls approached him on the set, asking if Tom Hanks was there. He was startled, wondering if he had suddenly been replaced by Hanks.
Answer: If the robbery had been successful, Jim would have been able to accuse Edward of robbing the house with his friends backing him up. Jim probably would have kept the car at a friend's house to avoid suspicion. Since the house belongs to Jim's father, nobody would question him going inside. If Jim and his friends tried to rob someone else's house, there would be the chance that somebody would be home or that a burglar alarm could go off and alert the neighbors and the police.
