The film, which was shot right after Silver Linings Playbook, follows industrialist George Pemberton (Cooper), whose life and timbre empire gets a little more chaotic when he marries the impulsive and seductive Serena (Lawrence).
So how was the shoot and the opportunity to work side-by-side after their celebrated work in Silver Linings?
"We had a lot of fun," Cooper told ET. "We got to shoot in Prague and ride horses."
"We had a blast," Lawrence added. "We always have a blast working together, obviously."
