In The Dark Knight, the opening bank robbery involves the Joker and a few thieves. When the jeep pulls up to pick up the Joker, he then puts on his mask and gets into the backseat.
Did the two thieves sitting in front not recognize the Joker? If not, this means the Joker planned the heist without actually being seen or known by the other thieves, how?
- He got someone else to plan the job as the "Joker", and told the thieves driving the car to pick up another thief(the real Joker) waiting for them on the corner.
- They also, probably didn't know each other very well, and most likely met a few days before the bank heist, as they were easily able to kill each other for a "bigger slice". I would assume if they did know each other well, they would be hesitant to kill a friend.
Based on the conversation in the jeep, they mock the Joker for "sitting it out, and taking a slice", which indicates they aren't aware the Joker is with them.
