Music From Mr. Bean's Holiday?

I was wondering if someone out there might know the answer to this. I recently saw the movie Mr. Bean's Holiday. In the movie there is a scene where he and the boy he is with act out the scene from an opera. I know I've heard this music before and not sure if it's the same music from the opera scene in Pretty Woman. Nonetheless, I am trying to find out the name of the song and what opera it is from. If anyone knows I would appreciate the help. Thanks!
