Noises Off (1992)

From Wikipedia:
The film follows the concept of a play within a play, in this case a dreadful farce called "Nothing On" — the type of production in which many doors continually open and shut. The setting has been transplanted from English provincial theater to Des Moines, Iowa, where a second-rate theatrical troupe is preparing to perform the Broadway-bound play...

The film opens with the final dress rehearsal before opening night, with the cast still forgetting lines, missing cues, and mishandling props. Lloyd is reduced to cajoling, yelling at, and pleading with them to get things right. Complicating matters are the personal problems and backstage relationships that have fostered jealousy and petty squabbling and intruded upon any professionalism this motley crew can muster.
