VIDEO : Joker And Harley Quinn Writers Want Duo To Kidnap A Celebrity

Uproxx reports Joaquin Phoenix?s 'Joker' is underway, while the Margo Robbie's 'Birds of Prey' spinoff is in development.

But there's also a Joker/Harley Quinn movie being written by Glenn Ficarra and John Requa.

The whole thing starts with Harley kidnapping Dr Phil. Played by Dr Phil hopefully. Because her and the Joker are having problems with their relationship...

We were doing a relationship movie but with the sensibility of a ?Bad Santa,? f***ed up, mentally deranged people. It was a lot of fun.
Ficarra

More details of the film coming soon...
