Holy cow, Batman. And Superman this time, too. There's some major movie excitement happening in East Lansing!

The production of "Batman v Superman: Dawn of Justice" has moved to the campus of Michigan State University.

There have been Ben Affleck (who's portraying Batman) sightings and Henry Cavill (Superman) sightings lately around MSU.

For those who've been on campus lately near the Broad Art Museum on East Circle Drive, they can't help but notice the activity and excitement around the building.

Rumor has it the museum is being used as a location for Lex Luthor's mansion in the movie.

The character of Luthor is played by Jesse Eisenberg, known for his starring role as Facebook founder Mark Zuckerberg in the 2010 movie "The Social Network."

"Batman v Superman: Dawn of Justice" will hit theaters May 6, 2016, according to Warner Bros.

Affleck Visits MSU Football Practice

Add another one to the list of celebrities who've visited Michigan State football in recent years.

On Thursday, Ben Affleck made a stop at the Spartans' practice. He's in town shooting "Batman Vs. Superman: Dawn of Justice."

MSU has welcomed other celebrities within the past few years, like "300" star Gerard Butler and Mike "The Situation" Sorrentino of MTV's "Jersey Shore" fame.

We're not sure what Affleck was saying to the team in the above photo. Maybe it was something about putting the boot on the throat when up by several scores in the fourth quarter or something about the four-team college football playoff?
