Batman wasn't originally supposed to be in the 'Batman v Superman' movie

Next March, we'll finally see "Batman v Superman: Dawn of Justice" when it comes to theaters, but it wasn't always planned to include the Caped Crusader.

According to an EW cover story on the highly-anticipated "Man of Steel" sequel, "Batman v Superman" was originally supposed to be just that, a sequel to 2013's Superman reboot featuring Henry Cavill where Metallo was set to be the main villain.

Batman was nothing more than a passing suggestion from director Zack Snyder to "The Dark Knight" trilogy director Christopher Nolan and screenwriter David S. Goyer during a meeting.

But of course, you can never just bring up Bruce Wayne and Batman when discussing Superman.

Via EW:

"'I remember we were talking about 'What's the next villain'" Snyder says. "'We can't do another alien invasion.' Brainiac was definitely down the road. Metallo, I think, was going to be the main bad guy of this movie." Then out of the blue, in a meeting with screenwriter David S. Goyer and executive producer Christopher Nolan, Snyder made a suggestion. "I said, 'What about at the end of the movie we do a scene where there's a crate full of kryptonite delivered to Wayne Manor.' Everyone was like... 'Okaay.' Once you say it out loud it's a problem because you can't unsay it."

And the rest of history.

We'll finally see the two do battle March 25, 2016 when "Batman v Superman" is released in theaters.
