Silver Linings Playbook is the story of two troubled people (Cooper, Lawrence) who form an emotional bond as they sort out personal problems.
In an interview with Flicks and Bits, Cooper said that the film is quite different from most Hollywood love stories.
"This movie is a very romantic movie I think as well," the actor said. "It centres around these people that are quirky, that you really haven't seen before. It's sort of a mixture of this genre that you haven't seen before because of the players in it."
Cooper also explained that Silver Linings Playbook carries a message about acceptance and kindness.
"At its core it's a movie about a guy who's able to be set free of this trauma that has occurred in his life, through the love he feels for another human being," he noted.
"And in discovering that he finds a serenity and peace within himself and hopefully a path to love himself."
Cooper recently praised his Silver Linings Playbook Lawrence, who he described as a "special" actress.
Silver Linings Playbook opens on November 21 in the US and the UK. Watch a trailer for the movie below:
