The Prestige was SUCH a good ending. And, of course, one must mention The Usual Suspects in any list about twists. 

Parasite was such a wild twist because it shifts the entire tone of the movie. Whenever I thought I knew the direction it was going, it was like OR SO YOU THOUGHT. Brilliant. 

okay so every m night shyamalan movie aside, When the Bough Breaks is a good one. 

My two faves: Memento and Charade. The latter is such a fun watch, particularly for an older movie. 

Don't say the twist, but I'd love to compile a list of movies that have twists and turns you could have never seen coming! There's of course Fight Club and The Sixth Sense, but here are a few of my personal favorites... 

The Prestige (another good magic movie with a twist is the Now You See Me series)

Searching (< if you haven't seen this it's SO good, completely done through webcam / cell footage and John Cho is just 👩🏼‍🍳😘🤌🏼) 

What's your favorite movie with a twist?
