It's all Moonshine (1979)

Hungary in the 1930s. The world suddenly changes around the peaceful office-clerk and regular, average petit-burgeois Kornél Cassius. Friends and relatives turn up in his home, who soon establish themselves there and even take the upper hand. They continue to arrive in increasing numbers, and turn the well-known objects and patterns of relationships upside down.

Unfortunately the movie It's all Moonshine is not yet available on HBO Max.
