"Justice League: The Flashpoint Paradox" -- the newest collaboration between DC Entertainment and Warner Bros. Animation -- finally has a trailer to go along with the snippets of information and screencaps that have hit the Internet over the past several months.

Geoff Johns and Andy Kubert's "Flashpoint" was DC's major summer event for 2011, and paved the way for the publisher's current New 52 continuity and largest publishing initiative ever, the New 52, which relaunched 52 titles as new #1 issues. Legendary Batman voice actor Kevin Conroy revealed his involvement in the project last year (and will be voicing Batman for the non-alternate universe version of the Dark Knight), joining Dana Delany as Lois Lane, Ron Perlman as Deathstroke and Vanessa Marshall as Wonder Woman.

When time travel allows a past wrong to be righted for The Flash and his family, the ripples of the event prove disastrous as a fractured, alternate reality now exists where a Justice League never formed, and even Superman is nowhere to be found. Teaming with a grittier, more violent Dark Knight and Cyborg, Flash races to restore the continuity of his original timeline while this new world is ravaged by a fierce war between Wonder Woman's Amazons and Aquaman's Atlanteans. With breath taking action and an all-star voice cast, it's a bold, emotional vision that will forever change the landscape of the DC Universe.
