It’s such a classic that you’d never think there was tension behind the scenes between Ferrell and director Jon Favreau. Rumors have persisted over the years, and the Old School star has spoken out to explain what actually happened. And then I think Jon would let me do my thing and be like, ‘OK, I see what you're talking about.’ He said the contracts had both Will Ferrell and Jon Favreau attached, but Ferrell “didn’t want the director,” so he walked. And while Jon Favreau and Will Ferrell were able to make it through one movie with their different approaches, it’s probably for the best that they parted ways afterward.
