Zack Snyder comments have changed yet again on how his new Superman film, Man of Steel, would relate to Warner Bros.' planned Justice League movie.  In March, he said Justice League's Superman and Batman would be different than the ones from Man of Steel and The Dark Knight Trilogy.  Then at Comic-Con, Snyder played coy and said they were just trying to get Superman’s house in order, and then see where it went from there.  Since then, Warner Bros. has set a summer 2015 release date for Justice League, and Man of Steel continues to fly towards its summer 2013 release.  In a recent interview, Snyder's latest comments make Man of Steel sound closer to Justice League than ever before.

Hit the jump for more.  Man of Steel opens in 3D on June 14, 2013.

Speaking to the New York Post [via The Playlist], Snyder said:

"I don’t know how Justice League is going to be handled. Honestly, I don’t. But Man of Steel exists, and Superman is in it. I don’t know how you’d move forward without acknowledging that."

That's a big jump from March when he basically said the DC Movie Universe would have two Supermen.  When asked about discussions regarding Justice League and Man of Steel, Snyder responded:

"Um, how can I answer that? I can’t really say anything to that, because that’s a big spoiler. I will say, yeah, they trust me to keep them on course."

This doesn't sound like Snyder being coy as much as he doesn't know, and Warner Bros. probably doesn't know either.  If Man of Steel is a success and audiences love new Superman Henry Cavill, then he'll likely crossover into Justice League.  Furthermore, having two Supermen could be confusing to audiences (although it would be amazing if Warner Bros. wanted to make a live-action Crisis on Infinite Earths adaptation even though that will in all likelihood never ever ever happen).

However, another issue could be tonality.  Judging by the trailer and everything we've heard from Sndyer and screenwriter David Goyer, Man of Steel is supposed to be a more "serious" take on the character.  Does that mean Justice League has to follow suit, or will another director try to mix it up?  Rather than having an Avengers set up where five movies can lay the foundation for a big crossover, Justice League has an odd relationship with a single movie, Man of Steel.  It will be fascinating to see how the pieces will come together.
