The most recent trailer for Batman v Superman: Dawn of Justice featured quite the climactic moment, with classic Superman baddie Doomsday making a huge, intimidating entrance — intimidating enough to elicit an “Oh, s—t” from Ben Affleck’s Batman before Gal Gadot’s Wonder Woman enters the fray to show off her impressive strength. And while the trailer appears to suggest that the Doomsday battle is the real climax, the film’s production designer says that the villain isn’t “the final act.”

In an interview with French magazine Premiere (via Heroic Hollywood), Batman v Superman production designer Patrick Tatopoulous spoke a bit about the introduction to one of Superman’s most formidable opponents. The trailer confirmed previous rumors about the creation of Doomsday and his connection to Lex Luthor and Zod, and Tatopoulous reiterates that a bit here (with some slight grammatical errors due to translation):

We are able to tell a story in a fresh way. Doomsday is an evolution essentially. Fans may be aware of the death of Superman story, but this is handled in such a new way. When the film is called Batman v or versus Superman, it really has a lot of levels to the meaning. Superman isn’t just killed off at the end of something. We see how he evolves as part of Lex’s plan to protect the world.

Seeing the Superman we know, be gone, and then replaced with this reproduction is really going to make fans think of how we look at these super beings. It was especially interesting to figure out, how would you create Superman from Zod… then how would that involve into Doomsday.

Superman fans are well-versed in Doomsday’s destructive and deadly potential, and given the source material and the ending of that trailer, it’s easy to assume that the battle will be part of the film’s big finale — but Tatopoulos cautions otherwise:

Doomsday isn’t just the final act. Those feeling they may know too much this early, are going to be in for a true surprise.

What on earth could that mean? Is there a bigger villain after the Doomsday fight? Is Tatopoulos referring to Lex Luthor? It seems as though director Zack Snyder may have a few surprises in store for us yet.

Batman v Superman: Dawn of Justice hits theaters on March 25, 2016.
