Warner Bros. has released box art and further details for the July 30 release of Justice League: The Flashpoint Paradox, the home video animated feature based on 2011’s Flashpoint miniseries. Casting was announced yesterday, with Justin Chambers and Kevin McKidd as Flash (Barry Allen) and Batman (Thomas Wayne).

According to comicbook.com, the special features include:

• A Flash in Time: Are there other dimensions? Can time travel get us there? And if The Flash existed, could he really travel through time? Interviews with experts in mythology, theoretical physics and top DC writers will examine the science and legacy of the storytelling behind the fiction.
• My Favorite Villians! The Flash Bad Guys: Acclaimed DC Comics writer Geoff Johns and others share their favorite Flash villains in this short film that gives viewers a glimpse into the Flash’s world through the eyes of some of the nefarious characters he has encountered over the past 70 years!
• A Sneak Peek at the next DC Universe animated movie: An in-depth look into the next DC Animated feature film, spotlighting the cast and crew.
• From the DC Comics Vault: Bonus cartoon episodes
• The Flashpoint Paradox Audio Commentary

Update: World’s Finest has more details including a synopsis:

When time travel allows a past wrong to be righted for Flash and his family, the event’s temporal ripples prove disastrous, creating a fractured, alternate reality where the Justice League never formed, and even Superman is nowhere to be found. Amidst a new world being ravaged by a fierce war between Wonder Woman’s Amazons and Aquaman’s Atlanteans, Flash must team with a grittier, more violent Batman and government agent Cyborg to restore the continuity of Flash’s original timeline.

Jim Krieg (Green Lantern: The Animated Series and Batman: The Brave and the Bold) adapted the script, with Jay Oliva (Batman: The Dark Knight Returns) directing and James Tucker (Superman: Unbound) producing.

So, what episodes from the vault would you like/expect to see? I’m hoping for “Speed Demons” from Superman, “A Mirror Darkly” from The Batman, “Requiem for a Scarlet Speedster” from Batman: The Brave and the Bold, and of course “Flash and Substance” from Justice League Unlimited. Though I can imagine they might go for alternate reality stories instead.
