Ring Dem Bells

The Colonel orders Mainwaring and the platoon to make a training film with a couple of well-known actors, but unknown to Mainwaring they are to play the Germans. Mainwaring refuses to take part but the rest of the platoon is still ordered to do so. When the filming is cancelled, Mainwaring and the men, still dressed as German soldiers, are spotted in the local pub and the alarm is raised.
