Lorens Marmstedt agreed to finance the filming of Bergman's experimental screenplay, which the director said was in large part exploring the question, "Is earth Hell?" Filming, on a very low budget of approximately $30,000, took place over only 18 days, using an
Expressionist style of cinematography; characterisation is minimal and the acting flat, in keeping with the emphasis on existential symbolism. At one point, in further distancing, Thomas and Birgitta watch a ridiculous silent film together. ==Reception==
