Franz Kafka's It's a Wonderful Life(1993)

Franz Kafka has been stricken with a serious case of writer's block on Christmas Eve. He's trying to get started on his latest short story, "The Metamorphosis", but he isn't sure what his protagonist Gregor Samsa should become. As Kafka struggles with indecision, he has to contend with a loud holiday party downstairs, several unexpected guests, and a sinister knife salesman who has a bone to pick with him.
