Which actor played the role of the Joker in the 2019 film "Joker"?

Which actor played the role of the Joker in the 2019 film Joker? Joaquin Phoenix. He plays Arthur Fleck, a mentally ill party clown and aspiring stand-up comedian whose alienation and mistreatment contribute to his transformation into the Joker.

Directed by Todd Phillips and co-written with Scott Silver, Joker presents an alternative origin story rather than connecting directly to an established Batman film continuity. The movie draws inspiration from 1970s character studies, particularly Taxi Driver and The King of Comedy, and places Arthur in a decaying version of Gotham City.

Phoenix's performance earned widespread praise and won him the Academy Award for Best Actor at the 92nd Oscars. The film also won Best Original Score for Hildur Guðnadóttir. It premiered at the Venice Film Festival in 2019, where it won the Golden Lion, before its October theatrical release.

The other options are actors who have also played the Joker in major productions: Jack Nicholson in Batman, Heath Ledger in The Dark Knight, and Jared Leto in Suicide Squad. Their performances belong to different versions of the character, not the 2019 film.
