Heath Ledger hid away in a motel room for 6 weeks to prepare for his role as the Joker

Heath Ledger, before his unfortunate passing, was known for intense method acting. He would completely bury himself into his roles, going through extreme measures to get in the mindset of the characters he was hired to play. Before filming his iconic role as The Joker in the Dark Knight, the second film in Christopher Nolan’s Batman trilogy, Ledger locked himself in a motel room for 6 weeks. He refused to leave or have contact with humans, and even went as far as peeing in milk jugs and drinking it.
