With principal photography about to officially begin this week in Detroit for the "Man of Steel" sequel, the stars and crew of the film gathered at a local bowling alley for a cast party Saturday night.

Stars Henry Cavill and Gal Gadot along with director Zack Snyder and production designer Partick Tatopoulos were spotted in downtown Detroit at the Garden Bowl, the oldest bowling alley in the nation, for a "Batman Vs. Superman" cast party.

ComicBook.com got to speak with Tatopoulos but would not give any details about the film.

Earlier in the week, Michigan publication MLive reported that Gadot, who is set to play Diana Prince and Amazonian Princess otherwise known as Wonder Woman, posted a Facebook message boasting that she's in Detroit and ready to begin filming.

"I can smell the weekend coming.. Any plans?" she wrote, which also stated that she was "near Rochester, Mich."

The still yet-to-be titled film will be the biggest movie filmed in Michigan as its budget reaches $131 million, according to the Michigan Film Office.

Last summer, the state's film office awarded the production team a $35 million incentive for in-state expenditures. The movie is also expected to create hundreds of construction jobs and roughly 6,000 jobs for extras, according to MLive.

Ben Affleck, who is taking on the mantle of Bruce Wayne, aka Batman, in the 2013 follow-up film, is expected to be staying in Detroit with his wife Jennifer Garner and their family "all summer" long during production, Garner said several weeks ago.

Last week, Warner Bros. announced that Affleck's Prohibition-era dram "Live by Night" would be pushed back because of his role in the "Man of Steel" sequel, according to The Hollywood Reporter.

The film, which has the star both directing and starring in, was originally slated for a Dec. 25, 2015 release but after the studio also moved "Batman Vs. Superman" up a year, the film now has a release date of Oct. 7, 2016.

Snyder's comic book epic is set for release on May 6, 2016.
