Warner Bros. Pictures wisely wasted until today, the day after April Fool’s Day, to release the first poster for Joker: Folie à Deux. If it had come out on April 1, no one would have believed it was the real thing. That’s how twisted the Joker is. Along with the poster, which has the Joker (played by Oscar winner Joaquin Phoenix) dipping Harley Quinn (Lady Gaga) while they dance, Warner Bros. also released the first audio clip from the sequel to 2019’s Joker.
