Before we get started here, if you’ve not seen Batman v Superman yet, do not read on. Zack Snyder has been talking to EW, and he told them exactly what the thinking was behind the ending of the film. He also mentioned just how the ramifications of the finale will play in to next year’s Justice League – Part One. We’re going in to full spoilers from this point forward, you have been warned.

One of the few shocks in Batman v Superman that wasn’t ruined by the trailers was the death of the Man of Steel. As you should remember, Superman sacrificed himself to stop Doomsday. It was certainly an interesting choice, and it left many scratching their heads. According to Snyder, his sacrifice was necessary both for this movie and future instalments.

“I felt like we had to kill Superman in this movie in order for us to have been serious with the entire premise of the film,” Snyder says. “And that’s not to say that he clearly is gone forever.”

The last shot of the film saw soil moving on top of Clark’s coffin. While that hinted at a revival for the last son of Krypton, it doesn’t sound like he’ll be making a speedy recovery in time to form the Justice League.

“I wanted Bruce Wayne to build the Justice League,” Snyder said to EW. “I just feel like Bruce Wayne having to go out and find these seven samurai by himself, that’s a lot more interesting of a premise.”

Snyder also went on to say that part of Justice League – Part One will involve the heroes searching for a way to bring back Superman.

“I felt like there’s a mythological journey for Superman,” Snyder added. “There’s the birth, death, and resurrection thing. And when you bring him back, who knows what he is when he comes back.”

If Batman is searching for a method of resurrection, could he go in search of the Lazarus Pit? It has brought back the dead in the past, but it rarely goes well. That could possibly tie in to the “Knightmare” vision that Bruce has, courtesy of The Flash. We’ll find out in November next year, when Justice League – Part One hits theatres.
