The LEGO Batman Movieis only a week away, and Warner Bros. has done a good job of keeping a lid on most of the voice casting. So far we knew thatWill Arnettwas Batman/Bruce Wayne,Michael Cerawas Robin/Dick Grayson,Rosario Dawsonwas Batgirl/Barbara Gordon,Ralph Fienneswas Alfred,Zach Galifianakiswas Joker,Mariah Careywas the Mayor, andJenny Slatewas Harley Quinn.

But the film has a much larger cast than those six characters, and now we know the full voice cast for the film. As you’ve seen from the trailers, Joker and Harley Quinn aren’t the only villains Batman will be fighting against (he likes to fight around). The cast list reveals thatConan O’Brienis voicing The Riddler,Jason Mantzoukasis Scarecrow,Doug Bensonis Bane,Zoe Kravitzis Catwoman,Kate Micucciis Clayface, andRiki Lindhomeis Poison Ivy. Additionally,Channing TatumandJonah Hillare returning to voice Superman and Green Lantern, respectively withAdam Devineon board to voice The Flash.

However, there are also some unexpected characters entering the Batman universe.SPOILERS AHEAD.

The cast list reveals that the film contains “The Ubers”, characters from outside the Batman universe. The film will also include Voldemort (voiced byEddie Izzard), King Kong (voiced bySeth Green), Sauron (voiced byJemaine Clement), and a character named “Phyllis” (voiced byEllie Kemper). It’s unclear how these characters will factor into the plot, and it’s possible thatThe LEGO Batman Moviecould pull a move likeThe LEGO Moviewhere we head into the real world and that’s how the crossover happens. Or, asThe LEGO Moviehas already established, worlds can intersect, and that’s how the “ubers” come into play.

The LEGO Batman Movieopens on Friday.

Here’s the official synopsis:

In the irreverent spirit of fun that made “The LEGO® Movie” a worldwide phenomenon, the self-described leading man of that ensemble—LEGO® Batman—stars in his own big-screen adventure.

But there are big changes brewing in Gotham City, and if he wants to save the city from The Joker’s hostile takeover, Batman may have to drop the lone vigilante thing, try to work with others and maybe, just maybe, learn to lighten up.
