Plus his films where he was only the producer haven't been films that have really burned up the box office. I Am Number Four, A Nightmare on Elm Street, Friday the 13th, The Unborn, Horsemen, The Hitcher, The Texas Chainsaw Massacre: The Beginning, and The Texas Chainsaw Massacre have not been game changing box office smash hits. Most of the films where he was only a producer just sort of came and went. Micheal Bay the director might fill theater seats but Micheal Bay the producer can't replicate those box office numbers under other directors. You sort of have to wonder also what are the Turtles odds of standing out when Marvel and DC are both gunning for Avengers and Batman levels of money again. It's going to take something pretty special to win the biggest box office prize and not be an also released that summer film.
