Penelope Cruz hates shooting love scenes in films, so she makes her co-stars laugh to help relieve the tension.
But Cruz didn't enjoy the experience and turned to humour to get through the testing shots.
She tells U.S. host Larry King, "It's always a very strange thing. I mean, we had the best director and I was in the best possible company, but it's always something strange. ... We laughed a lot together, because you have to bring humour to those situations."
Day-Lewis agreed: "We had to laugh."
