Moviegoers aren't the only ones who thought Michael Bay was done with the Transformers trilogy after the release of Transformers: Dark of the Moon. Bay himself thought so too, but then he decided to direct a fourth installment.
Bay tells The Huffington Post that the success of the Transformers ride at Universal Studios Hollywood inspired him to reclaim control over the franchise: "I thought I was done. Then the ride came out and the two-and-a-half-hour lines. And you're thinking, Oh my God, someone's going to take this over." He adds that "someone could come in here and screw it up, you know?"
Bay also compares his franchise to those of James Cameron and Peter Jackson: "It's like, when you look at what's going on in the film business with the franchise frenzy right now, why is Cameron doing two more Avatar movies? Why is Peter Jackson doing three more Hobbit movies that are in the same world as Lord of the Rings? When you have a franchise, it's very hard to give it up."
Bay is expanding his franchise even further by promoting a Doritos contest which allows the winner to not only direct the chip company's Super Bowl commercial, but also to work on the new Transformers film.
