Joy trailer: Jennifer Lawrence, Bradley Cooper reunite for fourth film
Based on a true story, Hunger Games star Jen plays a struggling single mother of three who invents the Miracle Mop and becomes a successful entrepreneur and president of her own company, as well as a regular on home shopping channels in the US.

It also stars Robert DeNiro.
The movie, named after Jen's character Joy Mangano, is written and directed by David O'Russell, who also helmed Silver Linings Playbook and American Hustle, which both starred Jennifer and Bradley.
As both those films garnered Oscar nominations and wins, the expectations are high for Joy.
Jennifer and Bradley also collaborated on the drama Serena, but that wasn't as well received by critics and didn't perform as highly at the box office as their previous films.
