The Dresser (1983)

In a touring Shakespearean theater group, a backstage hand, the dresser, Norman (Sir Tom Courtenay), is devoted to the brilliant but tyrannical head of the company. He struggles to support deteriorating star Sir (Albert Finney) as the company struggles to carry on during the London blitz. The pathos of his backstage efforts rival the pathos in the story of Lear and the Fool that is being presented on-stage, as the situation comes to a crisis.
