Nicola & Alans' opening credits, like all our opening credits, introduces the film and sets the tone for the movie. The dress shot in the background is a slow pan of Nicola's dress (each opening credit is personal to the couple). You'll notice that the name and the theme tune of the movie is "It's a beautiful Day", you see that the original version of the tune is used at the end credits
too. The clips are just a glimps of what's to come and the titles introduce the stars and co-stars... just like they do in the movies!
