He confirmed on Jim Rome that yes, it's a typical Disney film with a happy ending. His only mistake was saying all Disney films have a happy ending. I really don't think you can consider the ending to Old Yeller happy. Well, unless you hated the dog.
I mean beyond the happy ending. The girl shows up at his door claiming to be his daughter and he bonds with her. We all know full well the entire plot of the movie.
But like I said...I will still go and see it.
Don't forget Joe Kingman winning the Super Bowl, and marrying Roselyn Sanchez's character at the end of the movie.
