There's been a major celebrity sighting in Utah's Monument Valley where this star of money-making movies and popular TV shows is filming his next summer blockbuster.
This Hollywood big wheel is Optimus Prime, the semi-trailer truck leader of the Autobots in the "Transformers" films. And director Michael Bay is shooting part of "Transformers 4" along the Utah-Arizona border.
Paramount Pictures has released photos of a retooled Optimus Prime, along with some other new characters to the "Transformers" line-up. (The photos appeared first on the Los Angeles Times' website and on a site for OmniAuto, an Italian car magazine.)
