Zack Snyder has been buried up to his eyeballs working on Watchmen, but not so busy that he hasn't been able to talk about the film. Recently he sat down with Dark Horizons to discuss the movie, including specifics about the movie's ending, music used in the film and when we can see more trailers.

Regarding trailers, Snyder confirms that the next trailer will be attached to the release of Quantum of Solace, and that this trailer will provide a few more hints to the story of the film. Snyder says "I just saw the final version of it this morning... it's a little bit more story, a teeny bit more like a full trailer. This is much more like 'someone's picking off costume heroes'. You'll get a sense of the characters plight you know, 'we were supposed to make the world a better place... what happened to the American Dream'." Snyder also said that a third trailer should hit shortly after the new year.

Choosing an appropriately period soundtrack has been something of a joy for Snyder, he revealed. "That part is super fun, I love the exercise of having to go through the book and find songs from pop culture that fits scenes" he says. One song that gets a brief inclusion is 1984's '99 Luftballons' by Nena which he had to justify to one clueless onlooker - "someone said to me like 'I don't get why you put that song in the movie', and I said 'you know that song's about these red balloons getting away and causing nuclear war' and they're like 'Oh...huh'." Other songs that Snyder included in the soundtrack are Bob Dylan's "Desolation Row" and "All Along the Watchtower", Simon & Garfunkel's "Sounds of Silence", Nat King Cole's "Unforgettable", and at least one number by Nina Simone.

Finally, Snyder addressed the somewhat controversial ending to the film, which in the comics involved a gigantic, genetically engineered psychic squid creature. The film version replaces that part of the plot with a series of atomic explosions that turns society against the superhuman Dr. Manhattan. Some fans of the comic have been upset about the change, which Snyder is somewhat amused by. "The fans, god love 'em, they're all up in arms about the squid. What they should be up in arms about are things like shooting the pregnant woman, 'God is real and he's American', whether THAT's in the movie. That's my point of view, maybe I'm crazy." He does admit that the ending scenes with the main characters remain, as does the 'moral imperative' of the comic's ending.
