* ActorAllusion: In the film, Max and Diana refer to their affair as "a many-splendored thing" - an inside joke, since Creator/WilliamHolden had starred in ''Love Is a Many-Splendored Thing'' (1955).

* BeamMeUpScotty: The actual line from Howard Beale's rant is "I'm ''as'' mad as hell, and I'm not ''going'' to take ''this'' anymore!" Often misquoted as "I'm mad as hell, and I'm not gonna take it anymore!" Also, Beale doesn't shout it out the window; only his viewers do, although their wording differs slightly... which makes this case of BeamMeUpScotty understandable.
* CommonKnowledge: It's often claimed that a young Creator/TimRobbins plays one of the assassins in the final scene. Robbins is on record denying this, but it's been propagated everywhere from [=IMDB=] to Turner Classic Movies.
* DoingItForTheArt: 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 for the screen test.
* FakeAmerican: Australian Peter Finch as Howard Beale.
* UnintentionalPeriodPiece: Although parts could just as easily apply to the present day. Many of the changes to the station in general and the news in particular were meant to be overblown exaggerations of then-current trends, now they're things that happened thirty years ago and standard industry practices (other than the open terrorist connections and assassination).
** The movie's whole message of television and corporations as these amoral, unstoppable and dehumanizing things is kind of a 1970s thing. To be sure, private media conglomerates and ratings-chasing are still things, but nowadays it's more straightforward profiteering and yellow journalism. In other words, whereas Diane ruins media because she's a soulless automaton, Rupert Murdoch does it because he likes money.
** Screenwriter Paddy Chayefsky envisioned Creator/HenryFonda, Creator/JamesStewart, Creator/PaulNewman, or Creator/CaryGrant filling the role of Howard Beale. Creator/GlennFord, Creator/GeorgeCScott and Creator/GeneHackman also passed on it.
** Creator/SidneyLumet claimed that he wanted to cast Creator/VanessaRedgrave in the film, but Paddy Chayefsky didn't want her. Lumet argued that he thought she was the greatest English-speaking actress in the world, while Chayefsky, a proud Jew and supporter of Israel, objected on the basis of her support of the PLO. Lumet, himself a Jew, said "Paddy, that's blacklisting!" to which Chayefsky replied, "Not when a Jew does it to a Gentile."
** Paddy Chayefsky wanted Creator/WalterMatthau or Creator/GeneHackman for Max Schumacher. Faye Dunaway wanted Creator/RobertMitchum for the part.
** Paddy Chayefsky thought of Candice Bergen, Ellen Burstyn, and Creator/NatalieWood for Diana Christensen. The studio also suggested Creator/JaneFonda, Kay Lenz, Diane Keaton, Marsha Mason, and Jill Clayburgh for the role.
