Based on the Hasbro toy line that initially captivated kids in the 1980s, director Michael Bay’s TRANSFORMERS finds two warring bands of shape-shifting alien robots renewing their intergalactic conflict on Earth. While the Decepticons, followers of the malevolent Megatron (voiced by Hugo Weaving), strive to take over the planet, the Autobots, led by the valiant Optimus Prime (voiced by Peter Cullen), are intent on protecting humanity. When young Sam Witwicky (Shia LaBeouf) discovers that his new car is really the Autobot Bumblebee (voiced by Mark Ryan), it sets the stage for a massive giant-robot showdown.
