The countdown to DC Comics' Doomsday Clock event continues with the release of a new trailer hyping the first clash between the publisher's Watchmen characters and the heroes of the DC Universe.

In the new video, event writer and DC Entertainment Chief Creative Officer Geoff Johns shares more information on how he and artist Gary Frank have been developing their story. Additionally Johns promises fans even more information -- including new artwork -- will arrive this weekend during New York Comic Con.

Earlier this year, Johns explained the decision to introduce some of Watchmen’s characters (created by Alan Moore and Dave Gibbons) into the DC Universe. “Thematically, and metaphorically, there was no better choice than to use Doctor Manhattan. If you’re going to have a conflict between optimism and pessimism, a battle between the very forces of hope and despair, you need to have someone who personifies the cynicism that has leaked into our hearts and also has the ability to affect the entire DCU. It’s all paying off this November with Doomsday Clock.”
