Continuity mistake: When the wardrobe falls onto its side you can see that Frank hasn't broken the base. However, when he hides in it out on the landing, he is able to walk about inside it, moving the wardrobe with him.
Continuity mistake: When the other guest goes out into reception and asks "Mr. Bedford, all quiet?" in one shot he is wearing his dressing gown, but the next he's just wearing pajamas.
Continuity mistake: When Frank and Betty place their wardrobe down, it nearly goes through the floor because the boards are damp. First Frank tries putting wood under it (from the drawers), then after breaking the wardrobe door he swaps the wardrobe with another guest's. They place that wardrobe in the place where the damp boards were without putting any wood underneath, and don't seem to have any problems with the damp floor.
