The director wanted to make an independent film and collaborate with people who could work fast, like cinematographer Robby Müller and his handpicked crew who were non-union members. Friedkin shot everything on location and worked quickly, often using the first take to give a sense of immediacy. He did not like to rehearse but would create situations where the actors thought they were rehearsing a scene when actually they were shooting a take. Friedkin did this just in case he got something he could use. To this end, he let scenes play out and allowed the actors to stay in character and improvise. For example, during the scene where Chance visits Ruthie at the bar where she works, Friedkin allowed Petersen and actress Darlanne Fluegel to devise their own blocking and told Müller, "Just shoot them. Try and keep them in the frame. If they're not in the frame, they're not in the movie. That's their problem".
