Best movie mistakes of 1929
Continuity mistake: After trying in vain to sleep in the upper berth of a railroad car, Laurel and Hardy hastily get dressed and get off the train at the Pottsville station. As they watch the train pull away, they are wearing each other's derby. In the immediate close-up, each of the two is wearing his own derby.
Continuity mistake: Laurel and Hardy are in a rented boat with two young women. Laurel is seated behind Hardy. They each have an oar over the left side of the boat and the boat is going in circles as they paddle. After a brief shot of James Finlayson staring at them from the dock, both men's oars are suddenly on the right side of the boat.
