SPOILER ALERT : This article contains plot elements of the 3rd Transformers Live Action Movie. Shia LaBeouf told The Associated Press that Transformers 3 "brings the heart back to the franchise." He starts working on the third installment on Tuesday. The new script restores a human element that got lost in the second movie, LaBeouf said. "When I saw the second movie, I wasn't impressed with what we did," LaBeouf said at the Cannes Film Festival. "There were some really wild stunts in it, but the heart was gone." Michael Bay returns for the third time as director of the science-fiction franchise, which centers on dueling races of giant robots that bring their war to Earth. The next movie will have what the last one lacked - a sense of human consequences, LaBeouf said. On the second movie, "we got lost. We tried to get bigger. It's what happens to sequels. It's like, how do you top the first one? You've got to go bigger," LaBeouf said. "Mike went so big that it became too big, and I think you lost the anchor of the movie. ... You lost a bit of the relationships. Unless you have those relationships, then the movie doesn't matter. Then it's just a bunch of robots fighting each other." With "Transformers 3," the toll of the robot war will be grave for our planet, LaBeouf said. "There's going to be a lot of death, human death. This time, they're targeting humans," LaBeouf said. "It's going to be the craziest action movie ever made, or we failed." Transformers 3 is coming to theaters on July 1, 2011.
