Guy pretends to be The Joker

The Killing Joke (1988) and The Dark Knight Returns (1986), but Phillips and Silver otherwise did not look to specific comics for inspiration. Phoenix became attached in February 2018 and was cast that July, while the majority of the cast signed on by August. Principal photography took place in New York City, Jersey City, and Newark, from September to December 2018. Joker is the first live-action theatrical Batman film to receive an R-rating from the Motion Picture Association.
