"Physically, you've got to be an athlete to make it. The tempo and pace of the film is frightening. We literally rehearse movement like we rehearse dialogue, everything is on a count, like a ballet. There's extreme precision that goes into these things. You're talking about millions and millions of dollars that goes into these things. A lot of time is spent on bits and frames. Each frame is an all encompassing task and we all gotta work together," said Shia.
To coordinate all of the technical parts of the film the actors had to have a lot of trust in the people they were working with.
"You're talking about death here. You trip and fall in the wrong spot and it's a done deal. It's scary. But it's also this masochistic pride thing. I imagine what sports athletes have to go through. It's like a warrior samurai vibe," said Shia.
The first Transformers film earned more than $300 million. The sequel is expected to far outpace the 2007 movie.
