Heath Ledger directed both homemade videos that the Joker sends to GCN himself. The first video involving the fake Batman was done under Nolan’s supervision. Nolan thought Ledger had done so well with that sequence, he felt there was no need for him to be there when it came time to film the scene where reporter Mike Engel reads the Joker’s statement. He put his trust in Ledger and let him do whatever he wanted, ultimately pleased with the result after he’d seen the outcome.
