‘Spider-Man: Beyond The Spider-Verse’ Trailer Leaks Online, Co-Writer Chris Miller Says He’s “Not A Fan Of Leaks Of Unfinished Footage”

Leaked footage of Spider-Man: Beyond the Spider-Verse has made its way online and co-writer Chris Miller is putting them on blast.

A trailer for the third installment of the animated movie starring Miles Morales, which is set to hit theaters on June 18, 2027, was leaked on social media and Miller has already made his thoughts clear on the matter.

“Not a fan of unfinished, not fully rendered footage,” Miller posted on X, the microblogging platform formerly known as Twitter.

Sony Pictures and Marvel have not made a statement regarding the leak but Deadline has reached out for comment.

Earlier this year, Paramount faced a similar situation when a full version of The Legend of Aang: The Last Airbender leaked online by a fan. The fan was seemingly frustrated by Paramount’s decision not to release the film in theaters and opting for a streaming release.

The Legend of Aang: The Last Airbender was originally slated to premiere in theaters on October 10, 2025, but it was later pushed back to January 30, 2026. In December 2025, Deadline reported that the film, greenlit by the previous Paramount Animation administration, would not get a theatrical release after all. Instead, the film would stream on Paramount+ on October 9, 2026.

Following the leak, animator Julia Schoel, who worked on the film, took to X to express her thoughts, saying, “We worked on the aang movie for years with the expectation that’d we’d get to celebrate all of our hard work in theaters, just to see people unceremoniously leak the film and pass our shots around on twitter like candy.”

Paramount investigated the leak and arrested an individual in Singapore who gained illegal access to the film and if found guilty, the suspect could face up to seven years in prison, a fine of up to $50,000 or both.
