Hollis added,"Great to have Zack Snyder on campus. Is it a clue? I don't know ...."
Snyder will be filming parts of Batman Vs. Superman in Michigan, and it also looks like he was there to give the Michigan St. football players an early look at 300: Rise of An Empire, as Snyder is a producer on the film. The Michigan St. team is known as The Spartans.
"Along with @MSU_Football team, had a NYE opportunity to see a screening of the new 300: Rise of an Empire with Zack Snyder. Not Disappointed," Hollis added.
As Hollis notes, he saw the movie on New Year's Eve; it's unknown if the image is from that date or from something more recent as it's thought Batman Vs. Superman has seen a delay in production.
Warner Bros. announced a later release date for Batman Vs. Superman with news that production had shifted.
Snyder could be in Michigan scouting locations and such for pre-production.
"Batman Vs Superman" has a newly announced May 6, 2016 release also starring Ben Affleck, Henry Cavill, Gal Gadot, Amy Adams, Laurence Fishburne and Diane Lane.
