Over the course of its story, The Maze Runner films offered a number of memorable deaths, proving that characters on neither side were safe. Adapted from James Dashners best-selling novels, The Maze Runner saw its characters fight against the World In Catastrophe: Killzone Experiment Department, an organization that was experimenting on them. With The Maze Runner cast led by Dylan OBrien, the series was a huge success, grossing over $940 million worldwide. The Maze Runner 4 is currently in development and will likely help the franchise hit the $1 billion mark.
