Transformers: Age of Extinction hit theaters this weekend and was a huge box-office success.  The movie brought in an estimated $100 million in its opening weekend– destroying the competition.

One of the movie’s biggest stars is Optimus Prime.  The truck, a Western Star 5700, was developed specifically for the movie.

“When the producers of the film approached us to create the new Optimus Prime, we knew we already had the perfect truck in the works and that it would be an ideal partnership to showcase our dedication to engineering, design and building the most rugged and reliable trucks in the industry,” said Andy Johnson, brand manager for Western Star. “Being a part of the Michael Bay Transformers film franchise is a unique opportunity where vehicles are stars, and we’re thrilled that Western Star is a major part of this iconic franchise.”
