Heath Ledger
Also after he died, the movie The Imaginarium of Doctor Parnassus was first shown in movie theaters in 2009. Ledger was supposed to act as the main role of Doctor Parnassus, but he only filmed about half of the scenes before he died. The director for this movie, Terrry Gilliam, decided that the movie would be changed so that three other actors would also act as this character in some parts of the movie. The other actors were Johnny Depp, Colin Farrell, and Jude Law, who were all friends with Heath Ledger before he died.
