While Batman Vs. Superman isn't specifically mentioned by name, it's pretty obvious what movie a new extras casting call posted on the Michigan Film Office website is for.

The Warner Bros feature film extras casting call is for clean cut military and law enforcement types and business executives in suits over 18 years, both male and female. Of course, the first Man of Steel movie featured plenty or military and law enforcement types, as Superman's battle with General Zod wrecked havoc on Metropolis. With Lex Luthor already confirmed as one of the central villains for Batman Vs. Superman, it's also no big surprise that the film would need plenty of business executives in suits.

Another interesting observation from the casting call is that it specifically states in bold print: NO COSTUMES PLEASE! Evidently, they know people will figure out that it's a Batman Vs. Superman casting call, and they don't want anyone showing up to audition for an extras role in an Aquaman costume, thinking they are going to land a central role in the film.

The calls also notes that extras must be available to work in Detroit area locations between June and November 2014, which gives a good idea on how long Batman Vs. Superman will be filming in Michigan.
