Jared Leto in Suicide Squad
A crazy role requires appropriate preparation, and the role of the Joker in Suicide Squad is definitely crazy. Jared Leto followed Heath Ledger’s footsteps, and much like his predecessor, some would say he went a little too far during the filming of the movie.
Leto sent his costars creepy love letters, bullets and a dead rat. When things started to get out of hand, the production hired on-screen therapists for the cast members.
