By now, you may have seen the primeval clip of Sony's Gran Turismo for PSP commercial featuring Rhys Millen driving a Corvette ZR1 at Laguna Seca, while Tanner Foust does the very same thing on PSP from the passenger seat.

Well, Sony has prefabricated a "making of" movie about the commercial, and you can see to what lengths the company went to make the real-life action on the track match what was happening in the game. Foust is racing against a Ford GT, Nissan GT-R and an E30 BMW M5 in the game, so those same cars are on the track. Rod Millen apparently drove the GT.

In shooting the ZR1, says Stephanie Yoshimoto, senior product marketing manager for Sony, "we worked to replicate the camera used in the game. The cameras were mounted just as they would be in the game — third-person view, first-person view. That was the goal really to make sure we replicated the game with the actual commercial."

Foust, she says, picked up the game easily and didn't get carsick. "He could deal with being thrown from side to side at 130 mph, going through the corkscrew and all that."

The 30-second commercial is after the jump.
