Warner Bros. announced at Comic-Con 2013 that one of their next DC Universe animated movies will be Justice League: War, debuting on Blu-ray and DVD sometime in 2014. Although the studio still hasn't announced a release date, the first trailer has arrived from this superhero ensemble. Alan Tudyk and Jason O'Mara lead an all-star voice cast as Superman and Batman, who team up with Wonder Woman (Michelle Monaghan), The Flash (Christopher Gorham) and Green Lantern (Justin Kirk) to stop an alien invasion from destroying Earth. We'll keep you posted as soon as we have any official details, but, in the meantime, take a look at the first footage.
