Umberto Gonzalez at The Wrap:

Todd Phillips’ planned “Joker" origin movie will portray Batman’s arch-nemesis as a failed 1980s comedian who becomes the clown prince of crime after bombing with audiences, insiders exclusively told TheWrap.

Many fans scratched their heads when news first broke that Martin Scorsese, who has eschewed superhero films in the past, would be  a producer of the film. But his involvement makes more sense given his work on 1982’s “King of Comedy,“ which starred Robert De Niro as a deluded comedian who can’t catch a break. The Joker origin story will include nods to that film, insiders told TheWrap.
