Zantera had Memento on his list and LithoJazzoSphere had it on his honourable mentions.
I was having a look at the IMDB 250 top rated English movies and the only ones I'd previously ranked as 10/10 were the ones I mentioned earlier in the thread (LOTR, The Matrix, Terminator 2), plus The Bourne Ultimatum.
Ones that I'd given 9/10: The Shawshank Redemption, The Dark Knight, Goodfellas, Saving Private Ryan, Interstellar, The Green Mile, Gladiator, American History X, The Usual Suspects, The Departed, The Prestige, Whiplash, Memento, WALL-E, Joker, Toy Story 3, Up, Snatch, Batman Begins, The Wolf of Wall Street, The Truman Show, Kill Bill vol.1, Everything Everywhere All at Once, Hacksaw Ridge, The Grand Budapest Hotel, Stand By Me, Into the Wild, The Imitation Game, Sin City, Casino Royale.
So I guess those are my honourable mentions
But of course that's only those on the IMDB list, there will be others that I can't think of right now.
