Continuity mistake: At the races, Wimpy has Swee'pea at the line up board, asking which horse to bet on. As Castor walks in, the shot cuts to Wimpy at the board. The number 7 slot is empty, and no attendant is there. As the shots alternate between Wimpy and Castor, there is an attendant behind Wimpy erasing slot 7, starting to write, then gone again after Castor goes by. In the next moment, Wimpy is directly in front of the board asking Swee'pea. After picking Holy Moley, the next wide shot has the attendant back again with a name in slot 7.
Continuity mistake: At the betting window, Wimpy is holding the money he won with the top serial numbers toward his left side. When Olive grabs the money from him, she did so in a way whereby the money would not have been turned. However, the money is now the opposite way from how Wimpy held it.
Continuity mistake: In the beginning, there's a citizen ringing the bell. If you look carefully, the church appears to lit by strong daylight, but it's supposed to be stormy. After the bell ringer is done, the light strengthens as if the ringing awakens the town. The lighting on the church doesn't change at all.
Continuity mistake: When looking at the storm clouds in the beginning, the sun can be seen peeking over the clouds at the far right side of the shot. Then, after a flash of lightning, the sun is not only completely hidden by the clouds, the clouds at that spot are now much higher than they were. Also, the sun's position suggested late afternoon, yet the movie opens in the early morning hours, when Sweethaven is beginning its day.
Continuity mistake: At the end of the "Food Food Food" song, Popeye gives Wimpy the hamburger, and starts a conversation. There are two ketchup bottles on Wimpy's left. At the beginning of the chat, both bottles are nearly empty with just about a 1/2 inch in both. As the shots progress, the one nearest Wimpy goes from nearly empty to completely full and back again several times.
Continuity mistake: At the Oyls' house, during the engagement party, Nana Oyl gives Bluto a cup of tea, and moves off across the room. A few moments later after he drinks the tea, he starts to eat the teacup, and we see Nana's hands in frame on the right side where she served from. In the next shot, she's all the way across the room, too quickly.
