Exclusive Clip: From Justice League Action's "Galaxy Jest"

Today's DC All Access focuses, at least in part, on Justice League Action, Cartoon Network's new superhero series that draws from the deep bench of DC superheroes, supervillains, antiheroes and the like.

DC has provided ComicBook.com with an exclusive clip from the show, separate from the material that rolled out this afternoon on DC All Access. You can check it out below.

In the episode, titled "Galaxy Jest," Wonder Woman and Superman have to rescue Joker from Mongul. Meanwhile, Batman and Flash try to stop a massive laughing gas bomb that Joker has hidden away in Gotham City.

Any time The Joker gets cosmic, of course, things get kind of weird -- remember the whole "Emperor Joker" thing, where he found himself with some of Mr. Mxyzptlk's powers? That wasn't any fun for anybody except, basically, The Joker.

And while he's away, apparently that bomb attack is just something he wants to make sure everyone remembers him by. Because he couldn't just donate money to by a brick in the library sidewalk like everybody else.

In addition to regular cast members Kevin Conroy (Batman), Mark Hamill (The Joker), Rachel Kimsey (Wonder Woman) and Jason J. Lewis (Superman), "Galaxy Jest" brings in Futurama star John DiMaggio as Mongul.

Justice League Action airs Saturdays at 7:30 a.m. ET/PT on Cartoon Network.
