DC: What is the movie most referenced in other movies and how many movies was it referenced in?
This would be the movie TITLE that is said out loud by at least one character in another movie, hence the reference. I have a suspicion, but i’m not sure.

Wizard of Oz

Not sure how you could prove it

Answer by Dog
Maybe Wizard of Oz. At least people say “We aren’t in Kansas anymore…” in about a thousand different movies. I don’t think there is any one movie that is mentioned by name particularly more than other movies.

well you cant prove this but almost every sports drama and comedy uses the phrase “run forest, run!” so Forrest Gump would be a great answer to your question, and no way that it is wizard of oz
