It appears that David O. Russell has settled on his next project. Earlier this year, we learned that Russell was developing a biopic about Miracle Mop inventor Joy Mangano as a star vehicle for frequent collaborator Jennifer Lawrence. It looks like the film, titled Joy, has now been firmed up as Russell’s next movie, as 20th Century Fox has set a December 25, 2015 release date for the project. Long Island native Mangano was a single mother of three when she developed the prototype for her Miracle Mop in 1990. The product became a huge seller on QVC when Mangano went on air to pitch it, and she now has over 100 patents and a key role on the Home Shopping Network. Hit the jump for more.
