Lumet recalled that Chayefsky was usually on set during filming, and sometimes offered advice about how certain scenes should be played. Lumet allowed that his old friend had the better comic instincts of the two. Finch, who had suffered from heart problems for many years, became physically and psychologically exhausted by the demands of playing Beale.<ref>{{Cite web |url=https://www.youtube.com/watch?v=Sjx5L5Po4yI |title=Network (1976): Why The Acting Is So Good-Acting-CinemaTyler on YouTube |website=[[YouTube]] |date=November 17, 2017 |access-date=July 1, 2018 |archive-date=September 20, 2018 |archive-url=https://web.archive.org/web/20180920105934/https://www.youtube.com/watch?v=Sjx5L5Po4yI |url-status=live }}</ref>

There was some concern that the combination of Holden and Dunaway might create conflict on the set, since the two had sparred during an earlier co-starring stint in ''The Towering Inferno''. According to biographer Bob Thomas, Holden had been incensed by Dunaway's behavior during the filming of the disaster epic, especially her habit of leaving him fuming on the set while she attended to her hair, makeup and telephone calls. One day, after a two-hour wait, Holden reportedly grabbed Dunaway by the shoulders, pushed her against a soundstage wall and snapped, "You do that to me once more, and I'll push you through that wall!"{{Citation needed|date=March 2022}}

Lumet and cinematographer [[Owen Roizman]] worked out a complicated lighting scheme that in Lumet's words would "corrupt the camera". Lumet recalled: "We started with an almost naturalistic look. For the first scene between Peter Finch and Bill Holden, on Sixth Avenue at night, we added only enough light to get an exposure. As the movie progressed, camera setups became more rigid, more formal. The lighting became more and more artificial. The next-to-final scene—where Faye Dunaway, Robert Duvall, and the three network gray suits decide to kill Peter Finch—is lit like a commercial. The camera setups are static and framed like still pictures. The camera had also become a victim of television."<ref name="lumet" />
