EXCLUSIVE: Warner Bros and DC are in the early stages of another Batman Universe spinoff movie, this one telling the origin story of the signature villain The Joker. The studio has set The Hangover's Todd Phillips to co-write a script with 8 Mile scribe Scott Silver. Phillips will direct the movie, and Martin Scorsese will produce it with Phillips. 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.
I'm told that the intention is to make an origin story that isn't part of any other iteration. The Joker has memorably been part of two Batman movies in the form of Jack Nicholson and Heath Ledger, and was most recently played by Jared Leto in the first Suicide Squad film. He will reprise in the Suicide Squad sequel and the Harley Quinn spinoff, but this new film will launch the character with a different actor, possibly younger.
