At the end of the movie, Grandpa and Harry almost switch bodies. Actually, there is a sequel to the book where the dad and the son do switch bodies.

Marc McClure, who plays the delivery driver named Boris actually played Anna's (she was then called Annabelle) crush, Boris, in the original "Freaky Friday" (1976).

In the wedding scene at the end, Jamie Lee Curtis's husband, actor/director Christopher Guest, is in the crowd shots as a wedding guest.

Lindsay's mom is an extra in the wedding scene, she danced with someone ( it may have been Lindsay's dad, not sure) off to the right when you see Lindsay's back when she is dancing with Jake. She is also in the mid left front the 1st time they show the audience in the wedding guitar part. She is blonde and looks very much like Lindsay. To see pics go to www.llrocks.com
