Joker 2: First Look at Joaquin Phoenix Revealed (Photo)

While not part of the DCU, it was initially reported that director Todd Phillips' Joker sequel would begin filming in November. However, it appears production started a bit late, with Phillips posting a photo from the first day of shooting for Joker: Folie à Deux.

The sequel's title was officially announced in June, pointing to it including Harley Quinn alongside Arthur Fleck's Joker. A week later, not only was it confirmed that Quinn would be in it, but that she would be played by none other than Lady Gaga.

Reports indicate that it will be a musical from Quinn's perspective, likely a reversal of Fleck's twisted point of view from the original. So, despite a minor delay, filming for the film has finally begun as Phillips shows off a photo of one of its stars.
