Before CGI took over Hollywood actors used to speak lines instead of climbing up walls.
One of the master screenwriters in history was Billy Wilder. Dialog from his films is still being quoted.
Take your pick. “Double Indemnity” “The Lost Weekend” “Sunset Boulevard” “Ace in the Hole” “Stalag 17” “Sabrina” “Witness for the Prosecution” “Some Like it Hot” “The Apartment” “One, Two, Three”.
There’s more brilliant dialog in any one of these films than there is in all 642 Marvel films put together.
Once the script had been written, labored over for many weeks, Wilder never allowed the actors to change even one word. And the result was magic.
EDIT: I’m editing my OP for two important reasons. The first is that Billy Wilder had numerous writing collaborators who also deserve credit. In particular I.A.L. Diamond who worked with Wilder on 12 films.
The greatest tribute that Wilder paid to Diamond was in pointing out that, even though they had made a pact never to reveal which one of them wrote any specific line, Wilder broke the rule once by saying. “I didn’t write the line: “Nobody’s perfect.”
The second point, no less important, is that much of the greatest dialog in Hollywood history was written by a man who didn’t start learning English until he was almost 30 years old.
Billy Wilder and his six—count ’em six—Oscars.
