Pardon Us (1931)

Continuity mistake: The second-story room of the prison warden's daughter is on fire and she is screaming for help. Stan has trouble connecting a fire hose to a water valve and Ollie winds up completely drenched, but in all the following scenes where Ollie is using a ladder to try to rescue the woman, his clothes are dry.

Continuity mistake: After being arrested for selling homemade beer, Laurel and Hardy are taken to prison and brought into a room to have their photos taken. There is a large window behind the chair where each man is supposed to sit, but in the close-ups of Ollie, and then Stan, sitting in the chair, the window is gone and only a bare wall is behind the chair.

Continuity mistake: When Stan drops Oliver onto his head from the cell block during the riot, Oliver's head makes a crack in the pavement. In the next shot, there is a hole but the crack has disappeared.

Trivia: Director James Parrott has a cameo as the prisoner marching next to Oliver Hardy after Stan and Oliver are recaptured.

Trivia: This was Laurel and Hardy's first feature-length comedy film.
