2. The Gallows (2015)
Profit: $6,933,261
Budget: $100,000
Yet another horror movie, The Gallows has an abysmally low budget, the lowest of all the movies on our list. With such a small budget, even a little success at the box office ends up being extremely profitable and that is exactly what happened with The Gallows, which, like The Devil Inside, also received highly negative reviews.
