Off his medication and with nothing left to live for, Arthur kills his colleague who gave him the gun and makes his way to the studio, evading the detectives in a riot on a subway train. Appearing on the show in full makeup and insisting on being introduced as "Joker", he loses the audience's goodwill with his dark jokes. He admits to murdering the 3 men on the train and rails against society, saying that everyone's "awful", including host Murray. Saying "you get what you f***ing deserve" he shoots Murray in the head, then twice more. He's tackled and arrested, but Gotham city is rioting, and a man in a clown mask steals an ambulance and rams the police car transporting him. The protesters remove him from the car and encourage him to stand up. He rises, and realising his mouth is bleeding, he uses the blood to paint a smile on his face, revelling in the rioters' approval. We also see another rioter in a clown mask identifying the Wayne family leaving the cinema - he accosts them, repeating Joker's line about getting what you deserve, shooting them both and leaving Bruce standing over the bodies of his murdered parents.
Continuity mistake: When Joker is dancing on the stairs he throws his cigarette. Then when the cops arrive at the top of the stairs we see him blowing smoke from the same cigarette. Then the cigarette is gone again.(01:30:40)
Suggested correction:They purposely stuck the images in a way that it repeats itself over and over again. It's intentionally made in a way of not flowing straightforward.
Trivia: The font used for Live With Murray Franklin is identical to the Batman animated series titles. The name of the font is "Plaza," for those that might be curious.
Question: Spoiler! The scene at the very end, with Arthur locked up talking to the doctor/social worker - is that meant to be later, after he's been captured again, or is it a flashback to when he was hospitalised before, as was referenced earlier in the movie?
Answer:This is later, as the building appears to be Arkham. He's committed there instead of going to jail based on his insanity. It appears he is laughing about the death of Thomas Wayne, we see a flash of that scene again for a reason.
Chosen answer:I think it's meant to be deliberately ambiguous. I took at as him being locked up for his crimes, but others have commented that they think he was always locked up and the entire movie takes place in his head.
