Decades Of Cartoon Network Production Materials Leak Online

A large collection of production material associated with Cartoon Network shows has surfaced online, exposing artists’ working files and internal documents from some of the channel’s best-known series.

The reported leak includes material from The Amazing World of Gumball, Adventure Time, Regular Show, The Powerpuff Girls, and Foster’s Home for Imaginary Friends. The combined files reportedly total more than 200GB, though their full size and origin have not been independently verified. Google took down the original Google Doc linking to the files, but after hours of online circulation, the damage is done.

The files included storyboards, animatics, character model sheets, production guides, and editable animation assets. Some online posts describe source files from early Gumball episodes and layered background artwork. These tools and documents extend well beyond finished episodes or publicity material.

The timing is conspicuous. Paramount Skydance completed its acquisition of Warner Bros. Discovery on October 6, bringing Cartoon Network under the newly combined company, Skydance. Reports of the leak emerged within days, less than a week into the network’s new ownership, although no indication suggests the two events are related.

Paramount has already dealt with a major animation leak this year. In April, Avatar Aang: The Last Airbender was leaked online in full, months before its planned streaming debut. A suspect was later arrested in Singapore, while Variety reported that Paramount’s initial investigation found the vulnerability did not involve its own systems.

It remains unclear how the files were originally obtained, how they were accessed, and whether their acquisition predates the takeover. The public circulation of an archive does not, by itself, establish a recent breach of the company’s systems.

Production archives have considerable historical and educational value, documenting creative decisions and the labor behind animation. That value deserves recognition, but not as a reason to celebrate an unauthorized disclosure. Artists should have a say in how studios present their working material, and studios should provide responsible ways to preserve and study that history.
