Although both Jake and Allie are college students, Jonathan Taylor Thomas and Jessica Biel were both minors at the time of the film.
The film's trailer shows a little boy urinating on Jake's lap. That scene was cut from the film.
Jessica Biel (Allie) and Adam LaVorgna (Eddie) both starred in 7th Heaven (1996), in which their characters dated.
This is the first Live-Action Disney movie to use a variant of the Walt Disney Pictures logo, in this case the arch over the castle is made up of Christmas lights.
