Robert De Niro joins Joaquin Phoenix's Joker movie
Robert De Niro is in talks to take a key role in Joaquin Phoenix's new take on The Joker.
Phoenix will work with The Hangover director Todd Phillips on the project, which will serve as an origin movie for the character.
According to the Hollywood Reporter, De Niro is in talks to play a talk show host who is instrumental to the Joker's origins.
The movie, which is simply to be titled Joker and will be released into cinemas on October 4th in 2019, will have a more moderate budget of $55 million.
Phillips and 8 Mile screenwriter Scott Silver have been working on a script for a new film about Batman's nemesis since last year when the project was announced. Production is set to begin later this year.
Phoenix's movie stands apart from the wider DC universe, which also sees Jared Leto's take on the Joker set to get his own spin-off movie.
Leto will next be seen as The Joker in the Suicide Squad sequel in 2019 and is also expected to appear in the Harley Quinn spin-off and new project Gotham City Sirens.
No writer or director is attached to Leto's Joker spin-off as yet.
