YouTube adds then removes warning from Joker 2 trailer

At CinemaCon, Warner Bros. Pictures presented the first trailer for “Joker: Folie à Deux,” which went online shortly afterwards. Although the video was initially posted to YouTube without a content warning, the platform subsequently added one before deleting the warning a few hours later.

Via Variety, the warning said the trailer “may contain themes of suicide or self-harm.” Presumably this was in response to a scene in which Lady Gaga's Harley Quinn pantomimes shooting herself. This was an action that Joaquin Phoenix's Arthur Fleck performed a few times in the original Joker film.

In the following statement, a YouTube spokesperson blamed the warning on an automated system that incorrectly applied it to the video: “We discovered that our systems incorrectly applied the warning interstitial. The trailer remains available on YouTube without warning.”

The trailer highlights some key differences in the way Joker and Harley come together. In this incarnation, Harley (aka Harleen Quinzel) is a fellow inmate and not a doctor at Arkham Asylum. Regardless, Arthur and Harley seem to be immediately brought together in a crazy musical world of their own making. And in this timeline, there is no sign of a Batman who can stop them if they decide to break out together.

“Joker: Folie à Deux” hits theaters on Friday, October 4th.
