Jennifer Lawrence has teamed up with director David O. Russell again, attending a special screening of their upcoming film 'Joy' in London on Thursday.
The Oscar-winning actress says it's quite challenging for her to play the title role, a struggling Long Island single mom of three children.
"It was challenging but also exciting to find the personal and emotional balance between the woman who loves her children and loves being a mom but also has her own dreams and her own desires and ambitions and that's ok".
Loosely based on the life of inventor Joy Mangano, the film follows the story of a family across four generations, and how Joy eventually found success on a TV shopping network.
Director David O. Russell unveils his interpretation of the title role.
"I don't seek to make it biographical, I seek to make cinema that is surprising and that I haven't seen before, and in this case, my first picture with a woman at the center of it, a woman who has to earn her authority as the head of a family business from nothing, comes out of a metal garage her father runs, a bus garage, and that was very inspiring to me."
The film marks the third collaboration between Lawrence and Russell.
Lawrence has grabbed the Oscar Best Actress title for their first collaboration, 'Silver Linings Playbook' and was nominated for best supporting actress for their second film, 'American Hustle'.
This third collaboration has already earned the 25-year-old star a Golden Globe nomination.
'Joy' will open in North America on December 25th, and in UK on January 1st.
