The Joker origin movie will be set outside of the DC Extended Universe. Also, Wiseau has a distinctive laugh that would certainly differentiate himself from previous actors such as Jack Nicholson, Heath Ledger and most recently, Jared Leto.
It has been reported that Joaquin Phoenix is in talks to play The Joker in Warner Bros. and Todd Phillips' forthcoming yet-to-be-titled character origin movie, but it seems there is another interested party.
According to Variety, Inherent Vice and Walk the Line star Joaquin Phoenix has agreed to play the Clown Prince of Crime. Warner Bros. continues to develop a solo movie for The Joker, Batman and comicdom's greatest villain.
The film is expected to be set in the 1980s era, detailing how the Joker ended up as one of the most well-known comic book mastermind criminals.
Phoenix has been considered for another villainous DC role in the past: Lex Luthor in "Batman v Superman: Dawn of Justice", but passed on that role, which ultimately went to Jesse Eisenberg. However, WB has not confirmed it as such, and there was once a time when Phoenix was in talks to play Marvel Studios' Doctor Strange, so don't take it as a done deal.
Todd Phillips (The Hangover, War Dogs) is directing and co-writing the script with Scott Silver (8 Mile, The Fighter).
The Gladiator star, 43, is Phillips' top choice for the role in his DC movie, which will be produced by Martin Scorsese.
Phoenix has been the top choice to take on other superhero roles before, but has been resistant to joining any major studio blockbuster.
This will be the first film under a new banner that has yet to be named in which WB can expand the canon of DC properties and create unique storylines with different actors playing the iconic characters.
Phoenix now stars in the 2018 flick "Don't Worry, He Won't Get Far on Foot".
