Knives Out, and the sequel Glass Onion come to mind, if you like murder mysteries with some clever writing and a lot of humor
Unbreakable, Cabin in the Woods, Donnie Darko, Shutter Island, The Village and The Empire Strikes Back (Star Wars episode V) are all movies well known for plot twists
If you like the classics, Planet of the Apes (the 1968 original) is probably the most famous plot twist I can think of (also Soylent Green)
A personal favourite of mine is I am Legend, but only with the alternative ending, which is actually the real ending, closer to the book.
The endig the studio put in for the theatrical relese not only removes the plot twist, but the entire point and message of the movie.
Wathing the alternative (but original) ending takes this movie from mediocre to profound in the last 10 minutes. In my humble opinion
