Director Michael Bay returns to his blockbuster robots in disguise franchise with Transformers 4 starting production in May. The filmmaker recently revealed it will feature a completely new look and a 'smaller' approach.

"We're going to start off smaller. There's a brand new cast. To freshen the franchise we've redesigned everything from top to bottom. The history of the first three movies is still there, we start four years later and there's a reason why we're meeting a new cast. Mark (Wahlberg) is really excited about it and it's a great redesign. I said that 3 [which grossed $1.1 billion] was going to be my last one. Paramount was letting me do Pain and Gain and the Transformers ride was opening at Universal and it was bittersweet to think of passing it off. I wanted to set it up on a really sure footing and to bring someone else in on that, it would have been overwhelming."

When asked if the movie will reboot the franchise, the director confirmed it is not a reboot, but it is set four years after the events of Transformers: Dark of the Moon.

"No, that's wrong. We keep the Transformers the way they were, it's just four years later. There's a reason the Transformers are redesigned. We're trying to broaden the franchise and give it more places to go."
