Revealing mistake: There is an obvious stunt double for Grandpa during the fight scenes.
Revealing mistake: In the scene at the church, immediately after the girls were at the Suds Bucket, Mae is in the confessional when the priest drops his Bible. Mae steps out and kneels to pray as the priest opens the door to see who has just made their confessions. A closeup of the priest's face reveals that he has a "cowlick" (several locks of hair) hanging down in the middle of his forehead, but in the very next shot showing him in the background looking down at Mae, the lock of hair is suddenly gone.
