This past Wednesday, Bob Kane was honored with a star on the Hollywood Walk of Fame and Zack Snyder was there as a guest speaker. He did some interviews after the event, like this one where he reveals details about the new Batmobile. I came across another where Snyder reveals to 411Mania that he has a cameo in Batman v Superman: Dawn of Justice!
Jeffrey Harris: Last question, do you have a cameo in Batman v. Superman? Will we see you in the movie?
Zack Snyder: You won’t see my face. I pick some things up, but that’s it.
This wouldn’t be the first time Snyder put himself in one of his own movies. According to IMDb he had a cameo in Dawn of the Dead and Watchmen. As you’re watching Batman v Superman: Dawn of Justice keep an eye out. You may be able to spot Zack Snyder!
