A movie featuring the characters Joker and Harley Quinn is reportedly in development, with directors John Requa and Glenn Ficarra potentially involved. The project's details are unclear, with some outlets suggesting it may star Margot Robbie and Jared Leto, while others describe it as a separate entity from existing films. The tone of the movie is also uncertain, with one description likening it to a mix of "Bad Santa" and "This Is Us".
