Continuity mistake: Ferdie squirts oil on the face of Chuck. Chuck wipes his hand across his face and slaps Ferdie, leaving oil on his cheek. In a close-up, Ferdie cleans his face with a handkerchief but when he pulls the handkerchief away, there is no oil on it. The oil had obviously been cleaned off his cheek before the scene was filmed.
Continuity mistake: Chuck and Ferdie are among six people who a driver drops off at an abandoned lodge. In the long shots of the lodge, rain is falling at a very sharp angle but in the close-ups the rain is coming straight down.
