Director Tim Miller has reportedly left Deadpool 2 over creative differences with star Ryan Reynolds. While its unknown what those differences were specifically, Miller's exit was reportedly "amicable," according to Variety. Both Miller and Reynolds were confirmed to be returning for the sequel when it was announced back in April. The Miller-directed Deadpool hit theaters earlier this year and went on to become the highest-grossing R-rated movie of all time, earning over $780 million USD worldwide.
