It's a Party! -- Film Description:
"It's a Party! was shot with a stationary camera facing the hallway and living room of a small apartment. Actors continually move in and out of the frame, while three sound units capture every word of deathless dialogue about those perennial party topics: art, politics, and sex. Chaos begins with the arrival of the first guest just as the hostess finishes washing her hair; subsequent guests crowd into any room but the living room, and a riotous conga line attempts to incorporate an irate neighbour. As the party winds down, some uninvited guests arrive and chaos reigns again."
