David Ayer commented on the changes he made to The Fast and the Furious script and how he doesn't get credit for it, even though those story changes led to the franchise's $7 billion box office success. Ayer is known better as a director, having helmed intense such crime films as Street Kings and End of Watch, as well as the war movie Fury. He notoriously directed the DCEU's Suicide Squad, which is one of the most polarizing movies of the 2010s. However, he started out as a screenwriter. He famously wrote 2001's Training Day, and he also rewrote the screenplay for The Fast and the Furious.
