While Max and Charlie probably won’t be portraying Batman’s purple-spadexed Justice League cohorts Zan and Jan, the Wonder Twins aren’t the only twins in Batman’s DC Universe. While we can’t say for certain, Batman’s well-documented history of not working so well with others leads us to believe that the Carvers will play villains, joining the already cast Zoë Kravitz as Catwoman, Paul Dano as Riddler, John Turturro as Carmine Falcone, and Colin Farrell as Penguin.
As A.V. Club commenters point out, the brothers could play twin henchmen Max and Min or villains Tweedledum and Tweedledee. Another good guess would be that Max and Charlie, the latter of whom next appears on Netflix’s One Flew Over the Cuckoo’s Nest series, Ratched, and Ryan Muphy’s adaptation of The Boys in the Band, will play versions of the Trigger Twins. The original Trigger Twins—Walter, a sheriff, and Wayne, his quicker-shot brother—first appeared in 1951's All-Star Western #58 and lived on Earth-Two in “Crisis on Infinite Earths.” In 1993's Detective Comics #667, the twins were reimagined as a criminal duo named Tom and Tad who encounter the Azrael Batman and later join the Secret Society of Super Villains.
Though we’d love to be wrong and see Max and Charlie getting into high jinx with Gleek.
