Joker origin film to start rolling from september 

Golden Globe Award-winner Joaquin Phoenix's Joker origin film is set to go on floors from September. It will be helmed by Hangover franchise director Todd Phillips and co-produced by veteran filmmaker Martin Scorsese.

The film, which was supposed to kickstart in May, has been pushed to September due to undisclosed reasons. It is planned to be made at a much lower budget than is usual for adaptations of comics. 

The iconic super villain of the DC's Batman was first introduced in the 1966 film, The Batman. Though actors like Cesar Romero, Jack Nicholson and Jared Leto have played the role, Heath Leger's portrayal of the character in Christopher Nolan's Dark Knight went on to become the most loved. 

Almost a decade later, despite several Joker films being currently under development, Joaquin Phoenix's version is the one that is most anticipated. The film will be set in the 80s and it will trace Joker’s tragic backstory as a failed comedian, which also means that it will likely draw inspiration from Alan Moore’s seminal graphic novel, Batman: The Killing Joke. 

Though the film is an origin story of Joker, it will not be a part of the current DC cinematic universe. It is said to be an integral part of an alternate universe, tentatively called DC Dark or DC Black. 

Incidentally, Joaquin Phoenix was considered for the role of Doctor Strange in the Marvel Cinematic Universe, but the role eventually went to Benedict Cumberbatch.
