Bradley Cooper has described the set of Silver Linings Playbook as having an 'incredible atmosphere'.
The actor teams up with director David O. Russell for the movie and he says that the director creates a set where you feel like you can give everything.
Cooper told Total Film: "A David O. Russell set is an incredible atmosphere for an actor.
"It feels like a sporting event, that is the best way to describe it; you got to practice, you leave it all on the field and you sleep like a baby.
"After 33 days of that, you feel satiated."
Silver Linings Playbook is a big screen adaptation of the Matthew Quick novel of the same name and sees Cooper team up with Jennifer Lawrence and Robert De Niro.
The movie has already picked up some Oscar hype after being a huge success at the Toronto Film Festival earlier this year.
Silver Linings Playbook is released 21st November.
