Tom said this was the case, aside from Clark Gable being a reporter in It Happened One Night. He was wrong. All the King’s Men (1949) was about journalism. Jack Burden (John Ireland) was tracking political candidate Willie Stark (Broderick Crawford).
Gandhi (1982) also featured Martin Sheen and Candice Bergen as reporters.
In addition, All About Eve (1950) and Birdman (2014) each had elements of theater criticism in them.
That was the first one that came to my mind. The parallels between them are definitely visible. Not as much as some nominees like All The President’s Men, but definitely still a pretty similar core idea.
