The 61-year-old actor played a politician named Chris Marshall in the movie. Chris met and fell in love with the 55-year-old actress' character Marisa Ventura, who was a maid at the hotel he was staying in.
Why? Because he wasn't familiar with the intricacies of American politics.
"[I wondered] 'Now, who is this Republican senator?' My antennae for things American -- I think -- got better since. But then I think I was kind sometimes a little bit lost," he admitted.
The movie also allowed him to work with the late Natasha Richardson, who he described as a friend.
"I have a lot of happy memories of spending time with Natasha and [her husband] Liam [Neeson]. She was a wonderful, kind, open, generous host, wonderful actress, and I really valued her friendship," he said.
