U.S. audiences finally get the premier of "JL Action" this Friday, December 16 at 8PM CST/9PM EST on Cartoon Network.

In the clip below a humorously, even more heavily accented Constantine rounds up the League for their next mission. The description for the one-hour "Shazam Slam" episode reads:

"Shazam Slam," the villainous Black Adam battles Batman on the Rock of Eternity and unleashes a horde of Djinn determined to turn the Earth back to its pre-human, volcanic state. Affected by the otherworldly powers of these primordial monsters, Batman becomes possessed and is turned into a giant flying Batmonster laying waste to the Hall of Justice, with only Superman capable of taking the fight to the Dark Knight. One by one, the Justice League – with the help of Shazam (voiced by Sean Astin) and The Wizard (voiced by Carl Reiner) – must hunt down and defeat each Djinn in order to yet again save the world from destruction.

"Justice League Action" will then move to its regular Saturday morning time of 10:30AM EST on December 24.
