A good twist needs two things to work. Obviously whatever shocker's being played needs to be something genuinely surprising, but just as important is that the notion of a twist at all be unexpected. A surprise is all the more surprising if you don't know it's coming, after all. How many times have you seen a movie (or episode of a hit fantasy show) knowing there's a twist and thus had the full impact of it ruined?
To counter this, smart twist-makers will throw in a misdirect - a second twist that distracts your attention ahead of the real biggie. Sometimes the smaller one is a straight up fake-out, other times it's a small part of the larger picture, but played right it can insure surprises against blabbermouths (you can also make a movie that's good outside of a single rug-pull, but that's something for another time).
Other times, a movie will throw in two twists just because more is always better (hey, that's been Doughy's Pizza's business model for nigh-on twenty years, so who am I to argue). Whatever the reasoning, movies with two twists are curious beasts, so let's look at bit deeper and take in nine of my favourites.
