Using student actors from the Cassavetes-Lane Drama Workshop, shooting started in February 1957 in a largely improvised form. Cassavetes composed an outline for the film, but not a script. Cassavetes and assistant director/producer Maurice McEndree gave detailed instructions to the actors, constraining the situation to guide the story, with the words and the movements improvised by the actors. Cassavetes intended the story to evolve from the characters rather than vice versa. Three initial weeks of work was thrown out, the first week because of technical problems with quality, and the next two weeks because Cassavetes felt that the actors were talking too much. After they had developed their characters to the point at which they could portray emotion in silence, the actors improvised with more clarity and with a level of truth that Cassavetes found revealing. He was a demanding director who required a critical romantic scene to be performed more than 50 times before he was satisfied with the results. About 30 hours of film was exposed during several months of off-and-on shooting.
