Warner Bros is coming up with the origin story of the Joker, and trying to rope in Oscar winning star Leonardo DiCaprio to play the lead.

Legendary filmmaker Martin Scorsese has been involved as a producer of the movie. Sources told The Hollywood Reporter that Leonardo DiCaprio is being eyed to play the Joker. No offer has been made to DiCaprio, so this is not a done deal by any stretch; THR also reports that Scorsese’s deal is not finalized too.

Another reason behind getting DiCaprio on board is the fact that he and Scorsese have made five successful films together in the last ten years, The Aviator, Gangs of New York, The Departed, Shutter Island and The Wolf of Wall Street.

According to some online theories, the story might continue with another movie that will delve into the mad love between the psychopathic clown and his former psychiatrist Harley Quinn that ends up with their breakup.
