An insider for 'Justice League' says Superman was never going to wear the Black Suit in the new movie. A fan theory emerged following "Batman v. Superman: Dawn of Justice" that hypothesized a resurrected Superman would make his return along with the infamous Black Suit. Superman actor Henry Cavill even posted a photo of the dark costume.
