Warner Bros. unveiled the first footage of 'Joker: Folie à Deux' at CinemaCon.

The new trailer, once with a content warning on YouTube, presents a fresh dynamic between Joker and a Lady Gaga-portrayed Harley Quinn.

Both characters are depicted as inmates in Arkham Asylum, hinting at a dark, romantically charged narrative.

The sequel is slated for theatrical release on October 4.

Rumors suggest the film will feature approximately 15 musical numbers, drawing inspiration from classic Hollywood musicals.
