Bane’s voice on Gotham is different enough from Eduardo’s and creepy enough to be frightening without being difficult to decipher.
The trailer is also the first time that we really get to hear Bane’s voice, and I already love it.
In fact, Gotham star Ben McKenzie revealed that his “one beef” with The Dark Knight Rises was the voice.
Due to the mask, there’s always the risk that versions of the character will be too muffled for their words to be heard, let alone believably frighten the people around them.
