Diesel is not your standard “tough guy.” He is, first of all, a huge nerd. He’s not just an avid Dungeons & Dragons player; he wrote the foreword to the commemorative tome Thirty Years of Adventure: A Celebration of Dungeons & Dragons. He told Jimmy Fallon that the game inspired him to become an actor. He taught Judi Dench how to play. He’ll occasionally produce a critically-acclaimed, award-winning Xbox game. He made an animated film with the guy who created Aeon Flux. He loves Tolkien’s The Silmarillion. He’s spent most of his career desperately trying to make a movie about Hannibal’s failed conquest of Rome.
