Marc Maron is in talks to join Joaquin Phoenix in the forthcoming Joker Origin film.

The Crown Prince Of Crime film has seen its cast grow repeatedly having already recruited Robert De Niro who will play the role of a talk show host who is instrumental in the Joker’s origin.

Now Maron, known for his work with Glow, is believed to be close to agreeing to play the role of an agent working on the talk show in the movie.

Simply titled Joker, the Warner Bros. production will head to the cinemas October 4th 2019.

The film has been co-written by Phillips and Scott Silver, the man previously behind 8 Mile. Warner Bros. confirmed the news that Phoenix has signed on to the role and described the film as “exploration of a man disregarded by society [that] is not only a gritty character study but also a broader cautionary tale.”

Phoenix will become the fifth actor to portray the villain in live action with a new character and design set to follow. On top of that, there’s some speculation that Warner is plotting a second Joker movie with Jared Leto tipped to play the role.

It is believed the budget for the film is in excess of $55million which is a somewhat modest figure in comparison to other productions of the same ilk. Far Out Magazine reported the news that Phoenix had finally been confirmed to play the ‘Clown Prince of Crime’ in Todd Phillips’ Joker origin movie.

On top of that, Phoenix has revealed how he came up with the idea many years ago, he said: “Three or four years ago, I called my agent and said ‘Why don’t they want to take one of these characters and just make a lower budget film about it, a movie but a character study, and why not take one of the villains?’ And I thought, ‘You can’t do the Joker, because, you know, it’s just you can’t do that character, it’s just been done.”

“So I was trying to think of other characters, and he said ‘I’ll set up a general meeting with Warner Bros.’ And I said ‘I’m not gonna go, I can’t go to a general meeting.’ So I completely forgot about it, and so then I heard about this idea, I was like, ‘Oh that’s so exciting, that’s the kind of experience I wanted to have, with a movie based on a comic character.’ I felt like you could get something on screen.”
