In the book he re-tells numerous tales of his amusing escapades with Flynn during the 'Golden Age' of Hollywood and of the movies they made together, including how the famous Arrow Splitting scene was filmed in The Adventures of Robin Hood. Wiles documents numerous escapades with Flynn and it is interesting to note that whilst Buster managed a whole book on Errol, Flynn didn't manage a line on Buster in his own infamous autobiography My Wicked, Wicked Ways.
