Robert Deniro is in talks to join Jlaw for David ORussell's next film Joy, which will be about Joy Mangano, the inventor of the Miracle Mop.
The Source wrote, "Mangano (being portrayed by Lawrence) is a fixture on the Home Shopping Network with her many inventions, though the mop was her ticket to fame and fortune. She began her inventing as a teen and kept on dreaming and tinkering while still a single mom raising three kids."
Deniro will play Mangano's father.
The script was originally written by Bridesmaids writer Annie Mumolo but will be rewritten by David ORussell. Shooting will start in early February.
