9. Why Sonny And Cher?
The choice to use Sonny and Cher's I Got You Babe every morning Phil awakens was an early one: apparently it was in Danny Rubin's wildly different first draft, and was one of the few specific details that actually made it through to the final version. But why was it so perfect? Rubin answered that particular question during a Reddit AMA:
"Here's why I thought of it: if you listen to the recording at the very end it sort of winds down with a big slow "I got yououououou baaaaaaaabe." You think it's over, then it creeps back in: "I got you babe! I got you babe! etc" I thought this repetition was perfect. The timing never worked out for them to use it in the movie that way, but I guess because it's a love song and because even though it's catchy it would drive you crazy after a while, it was always a good idea."
