Though "Batman v Superman: Dawn of Justice" doesn't premiere for another three months, it appears that some European websites are already selling tickets for the film. DC Comics Movie (via ComicBook.com) points out that one such site in Germany appears to have revealed the runtime for the Warner Bros./DC Entertainment movie.
According to the site selling the tickets, "Batman v Superman" will run 151 minutes, or two hours and 31 minutes. That makes it about eight minutes longer than "Man of Steel", which had a runtime of 143 minutes, or two hours and 23 minutes. However, it's worth noting that films can sometimes have different runtimes in European countries than they do in the United States.
We'll find out for sure when the Zack Snyder-directed film, starring Ben Affleck, Henry Cavill, Gal Gadot, Jesse Eisenberg and Amy Adams, opens on March 25, 2016.
