In 1956, Peck made a foray into the film production business, organizing Melville Productions and later, Brentwood Productions. These companies produced five movies over seven years, all starring Peck, including "Pork Chop Hill", for which Peck served as the executive producer. The films were observed by some as becoming more political, although Peck said he tried to avoid any "overt preachiness". In 1958, Peck and good friend William Wyler co-produced the western epic "The Big Country" (1958); separate from Peck's production company. The project ran into numerous issues;Wyler and Peck were dissatisfied with the script, which underwent almost daily revisions, causing stress for the performers. Peck and the screenwriters ended up rewriting the script after each day's shooting, causing stress for the performers, who would arrive the next day and find their lines and even entire scenes different than for what they had prepared. There were disagreements between director Wyler and the performers, resulting in Peck storming off-set when Wyler refused to re-shoot a close-up scene. Peck and Wyler's relationship remained strained for three years after production. Peck said in 1974 that he had tried producing and acting simultaneously and felt "either it can't be done or it's just that I don't do it well".
