Bruits de coulisses

The movie's title "Noises Off!" is a stage cue used by playwrights in plays to indicate noises that occur offstage.

When the viewer see the show from the stage, fake walls are visible behind all the doors. When the viewer sees the show from backstage, those fake walls are missing from all the upstairs doors, although present for the downstairs doors. This is not actually a mistake; this is how an actual stage production is presented, and the top floor of the set rear needs to be seen clearly or half the action would be obscured.
