Short answer
There is no permanent URL for the latest Joker trailer. Trailer links change with each release, and reuploads copy the file under new addresses. The stable source is the studio channel that posted the trailer first. For Joker films that channel is Warner Bros. Pictures, with DC posting a second copy.
Which Joker trailer you mean
Two films carry the name, so confirm the target before you search.
- Joker (2019), directed by Todd Phillips, with Joaquin Phoenix. A teaser ran in April 2019. A final trailer ran in August 2019.
- Joker: Folie a Deux (2024), the sequel, with Phoenix and Lady Gaga. The first trailer ran in April 2024. A second trailer ran in July 2024.
Exact publish times for the 2024 clips vary by region and by channel. I cannot confirm a minute-level timestamp for each upload.
How to find the current link
- Open the Warner Bros. Pictures channel on YouTube.
- Search the channel for "Joker trailer" and sort by upload date.
- Match the runtime and title card to the film you want.
- Copy the address from the address bar. That is the URL to share.
Do the same on the DC channel as a cross-check. If a clip appears on a third-party channel but not on either studio channel, treat it as a copy. Copies get pulled, so a link from a fan page can go dead without notice.
Signs a trailer link is not official
- Channel name differs from the studio name.
- Video is mirrored, cropped, or carries a reaction overlay.
- Description is empty or filled with unrelated text.
- Comments are off on a new upload.
Studio uploads run in 16:9 or in a labeled vertical cut, carry a rating card, and list cast and crew in the description.
What a trailer URL will not give you
A trailer link plays a two to three minute clip. It does not carry the feature, a download, or a stream. Pages that promise a full film behind a trailer address are not studio pages.
