Gary Oldman praised Heath Ledger’s performance as the Joker in 2008’s *The Dark Knight* as an “extraordinary” achievement, comparing it with landmark work by Jack Nicholson and Al Pacino. The article argues that Oldman’s assessment underscores the enduring importance of Ledger’s portrayal, which became one of modern cinema’s most recognisable performances despite the actor’s death before the film’s release.

Oldman said great actors occasionally “go through the sound barrier”, citing Nicholson in *One Flew Over the Cuckoo’s Nest* and Pacino in *Dog Day Afternoon* as examples. He believed Ledger reached that level by finding something uniquely unsettling and compelling in the role; Ledger later won a posthumous Academy Award for Best Supporting Actor.
