In my unscientific research, I collected 11 recent 100-best quizzes and compared the movies I'd seen across all of them.
Two movies made it onto 6 lists: Alien and Spider-Man: Into the Spider-Verse.
Four movies made it onto 5 lists: Pan's Labyrinth, Pride & Prejudice, Shrek, and Shrek 2.
I think the ones across 4 lists are the most interesting, but there are gems everywhere.
6 Lists: Alien and Spider-Man: Into the Spider-Verse
5 Lists: Pan's Labyrinth - Shrek 2
4 Lists: The Addams Family - Rogue One: A Star Wars Story
3 Lists: Anastasia - 10 Things I Hate About You
2 Lists: Aliens - 2001: A Space Odyssey
1 List: Across the Universe through the end
