David Leitch has revealed his reasons for stepping down from directing Jurassic World 4, explaining how the decision was one that came down to doing what was right for the movie. The Deadpool 2 helmer wanted to emphasize that there was a conversation between himself, Steven Spielberg and Frank Marshall, and in the end, he was happy to step away from the film, knowing that it could allow someone else with the same vision to take over the next installment of the dinosaur franchise.
