<P> The scene where Nick sees Elizabeth and leans over in the elevator is a repeat of Cary Grant and Irene Dunne's classic scene from My Favorite Wife . </P> <P> Principal photography started on July 15, 1997, in London, United Kingdom, and continued in Napa Valley, San Francisco, Lake Arrowhead, and Los Angeles, California . </P> <P> The song used in the opening sequence in which glimpses of Nick and Elizabeth's first wedding is seen is Nat King Cole's "L-O-V-E". The song used in the end credits, in which photos of Nick and Elizabeth's second wedding is seen, is his daughter Natalie Cole's "This Will Be (An Everlasting Love)". </P> <P> The instrumental music featured prominently in the hotel scene where the girls and their parents cross paths serendipitously is "In the Mood", which was previously made famous by the Glenn Miller band . Later in the hotel, Hallie sings a few bars of "Let's Get Together", a tune from the first version of the film that was a hit for its star, Hayley Mills . The song is also quoted over the Walt Disney Pictures logo, and at the end of Alan Silvestri's closing credits suite . </P>
