General Motors have posted a video on You Tube covering General Motors Advance Design Center, featuring the design process of Transformers: Age Of Extinction Bumblebee; a Concept Chevrolet Camaro.

Back in March it was reported that a Paramount Pictures crew had visited GM's Grand Blanc Weld Tool Center plant as a possible locations for the fourth live-action Transformers film.  However it is now being reported by mlive.com that the location will not be used for the movie due to the film crew's schedule and the timeline for General Motors Co. to clear out the, soon-to-be-closed, Grand Blanc Weld Tool Center not being compatible according to Robert Wheeler, a spokesman for GM.

From The Hollywood Reporter:

Bay's robots in disguise boost GM profile
Survey: 'Transformers' car characters more popular than film's stars

From the outset, GM was thrilled with the starring roles that director Michael Bay orchestrated for four of its vehicles in his summer blockbuster "Transformers" despite some media and blogger criticism that the integrations went too far and basically served as commercials for the carmaker.

Now with the release of market research data from GM on the impact of its placement in the film, it appears there was indeed little consumer backlash against the integrations, which were widely considered among the highest profile and most significant film roles for an auto manufacturer, or any advertiser, for that matter.

According to the market research, Autobot Bumblebee, who spent much of the film as a Chevy Camaro, was the film's favorite character, beating out real-life stars Shia LeBeouf and Megan Fox and even Autobot leader Optimus Prime. Ninety-four% of moviegoers surveyed rated their opinion of Bumblebee as excellent or very good, compared with 91% for Optimus Prime, 83% for LeBeouf, 82% for Fox and 69% for Jazz, Ratchet and Ironhide -- played by a Pontiac Solstice, a Hummer H2 and a GMC Topkick, respectively, that transform into Autobots.

"This is one of those rare instances when our product was actually a key character in a movie," said Dino Bernacchi, associate director of marketing alliances and branded entertainment at GM. "When 94% of all moviegoers questioned said their favorite character in the film was Bumblebee, I think that just shows the power of what this movie was and what it did for us."

The data, compiled by an independent market research firm based on interviews with 1,350 U.S. moviegoers before and after seeing the film in theaters, demonstrated that respondents were 70%-90% more likely to consider purchasing the Camaro, Solstice, Hummer H2 and GMC Topkick after seeing "Transformers." And moviegoers' opinions of the GM vehicles also shot up drastically, with a 144% improvement in their opinions of the Solstice -- which has only been on the market since 2005 -- and a 72% improvement in audience views of the Camaro. Opinions of the Hummer H2 and the GMC Topkick improved by 65% or greater.
