PONTIAC, MI -- When "Batman v Superman: Dawn of Justice" hits theaters in 2016, the Made in Michigan product movement should get a nice PR boost.

Show cars, set building and transportation was all provided by skilled people with ties to the state, Michigan Motion Picture Studios (MMPS) CEO Linden Nelson told MLive.com.

"There were days where there were over 2,000 Michigan workers on site in this building," Nelson said.

As reported earlier, MLive hasn't been able to confirm details on the Batmobile or any of its suppliers because of conflicting information.

A GM official told MLive in September the company had no involvement in the project.

GM, however, helped design some of the cars seen in the Detroit-shot "Transformers: Age of Extinction."

"But the new Batmobile is not us, ironically," said David Barnas, at GM Design Communications. "That rumor has been going around for a while."

Fans will have to wait until March 25, 2016 to see the final "Batman v Superman" product. The film stars Ben Affleck as Batman and Henry Cavill as Superman.

Gal Gadot is Wonder Woman, Amy Adams is Lois Lane and Jesse Eisenberg plays the role of Lex Luthor.

"All the stars loved the experience; everyone was great to work with," Nelson said. "They all loved to check out The D (Detroit)."

"Batman v Superman" filming moved from Metro Detroit to Chicago late last month and will eventually go from there to New Mexico.

The Michigan Film Office confirmed the film's estimated budget at about $131 million. It is considered the largest ever for a movie in the state.

Nelson said he's hopeful he will get more superhero films because he considers work on "Batman v Superman" a success.
