The new Joker: Folie à Deux trailer is a show stopping ride through Harley and Joker's twisted romance – but it's also seemingly hiding another Batman villain in plain sight.
In one moment in the trailer, while Joaquin Phoenix's Arthur Fleck is seated in the back of a car, a voiceover from an unknown character can be heard. Click the closed captions on the video, however, and you'll see this mystery man is identified as none other than Harvey Dent, AKA Two Face.
