* 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 Tim Robbins 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.
* FakeAmerican: Australian Peter Finch as Howard Beale.
* RetroactiveRecognition: Amusingly, You can spot a young [[Series/LoisAndClark Perry White]] among UBS's news staff.
* 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.
