Faye Dunaway would later say that this was "the only film I ever did that you didn't touch the script because it was almost as if it were written in verse." She was as happy with Sidney Lumet as with the writing, describing him as "one of, if not the, most talented and professional men in the world.

Not a minute is wasted while he's shooting and that shows not only on the studio's budget but on the impetus of performance."
Peter Finch was desperate to win the role of Howard Beale once he had read the script. He even offered to pay his own airfare to New York City for the screentest. But Sidney Lumet was concerned about Finch's Australian accent. Finch won the part after sending Lumet a recording of himself reading the New York Times with a perfect American accent.
According to Sidney Lumet, the "Mad as Hell" speech was filmed in one and a half takes. Midway through the second take, Peter Finch abruptly stopped in exhaustion. Lumet was unaware of Finch's failing heart at the time, but in any case, did not ask for a third take. The complete film features the second half of the first take and the first half of the second take.
