Cooper is reuniting with Lawrence and director David O Russell in "Joy" after their previous hit ventures "Silver Lining Playbook" and "American Hustle".
Cooper and Lawrence's on-screen chemistry has been much praised. The 40-year-old actor said the actress is the "best at what she does," reported Contactmusic.
"She's kind of the best really at what she does. She has this ability to dive into a situation and imagine every circumstance and make it real and you believe what she's saying and the camera loves her, you cant take your eyes off her. She just has this very grounding, very rooted way of walking through a movie."
"The same thing I encountered with Robert De Niro. I found them to be very similar in terms of the way they approach the work and I think that's partly why David works with them again and again. For me to be able to make a movie with them either one of them, I would do anything.
