Do you recognize the accordion player?
First let me say that I love this movie, and it's one of my husband's favorites! We've watched it many times over the years.
When they are going to get married ("Goody Two-Shoes and the Filthy Beast?!"), the chaplain arrives with an accordion player. A few years ago, we realized who that accordion player is---it's Robert De Niro!
I looked him up on IMDB, and it doesn't show Father Goose in his credits, but you can pause the DVD-----and it is definitely him! I think it's always neat to see stars who are famous nowadays in small roles in older movies. (Sort of like Robert Duvall in To Kill A Mockingbird--what a surprise the first time I saw it after seeing so many of his films).
Anyway, check it out!
