Split
M. Night Shyamalan is no stranger to working with minuscule budgets when directing horror films, so it wasn’t as much of a surprise when he turned a $9-million budget into a $278.5-million success. Fans were shocked to learn that 2017’s Split was created on hardly anything, at least by Hollywood standards.

The strangest part about Split was that he didn’t receive a single penny from studios. Instead, he funded the entire project using his own hard-earned cash, and it’s safe to say that it definitely paid off. Opinions were split between the movie’s incredible story and its misleading portrayal of mental illness, but in the end, his investment more than paid off.
