Super Size Me (2004)
Many hit documentaries could make this list of movies that made 100 times their budget, since documentaries usually don’t cost a lot of money. To introduce the genre, we’ll be using one of the most famous documents, and also one that provides particular bang for the buck. That would be it Super Size Meby Morgan Spurlock, who tragically died of cancer last month aged just 53.
Helping to popularize the stunt documentary subgenre, Spurlock ate only McDonald’s for a month to see what it did to his health. It got a lot of people talking, changed the minds of some about fast food, and effectively ended the Super Size option at McDonald’s and similar options elsewhere. Oh, and it made a lot of money.
On a budget of $65,000, it grossed $22 million.
