Sean Gunn has been cast as Maxwell Lord, an evil businessman and frequent adversary in the DC Universe. Pedro Pascal played the character in the film ‘Wonder Woman 1984.’
In this new DCU, Maxwell Lord will be “referenced in the background” of James Gunn’s SUPERMAN LEGACY. Though it is currently unconfirmed that Sean Gunn will make a cameo in the film. But he will definitely appear as Maxwell Lord in future DCU installments.
Now Sean is James Gunn’s brother, and tends to show up in his films. So I’d bet my bottom dollar that he appears in Superman Legacy as well. Otherwise, why cast him now… I’m just saying.
