Dexter’s Laboratory creator Genndy Tartakovsky is one of animation’s most recognizable auteurs — the mind behind cult favorites such as Samurai Jack, Star Wars: The Clone Wars, Primal, and Unicorn: Warriors Eternal. Yet his projects often only receive widespread acclaim after they’ve ended or been cancelled, leaving him repeatedly in the position of fighting to get passion projects made.

Last Friday Tartakovsky shared test footage for a prospective film titled The Black Knight — not to be confused with the live-action comedy of the same name — revealing that the project stalled because executives worried it wouldn’t draw theatrical audiences. The proof-of-concept shows a hulking 20-foot iron knight pitted against a lone combatant doing everything in her power to dismantle it. The sequence carries a Soulslike intensity, and Tartakovsky appears to be hoping that public enthusiasm might persuade a studio to take another look.

In his post he wrote that development began “about six years ago.” Though the studio embraced the concept, executives ultimately passed, prompting Tartakovsky and his team to produce a rough, low-budget test to demonstrate the idea. He coyly revealed one production detail: the 20-foot knight would have been a mechanical suit operated from within by ropes, pulleys, and levers against a roughly 14th‑century backdrop. Borrowing a tactic associated with Ryan Reynolds’ effort to rally fans for Deadpool, Tartakovsky published the reel publicly in hopes that fan excitement could change a studio’s mind.

Tartakovsky’s career has been marked by both widespread influence and recurring institutional resistance. Shows like Samurai Jack and Star Wars: The Clone Wars left an indelible mark on viewers and on action storytelling in animation, but they didn’t always receive immediate mainstream validation. His later, more adult‑oriented work — including the Emmy-winning HBO series Primal — demonstrates how he followed his audience into more mature territory, yet even established creators sometimes have to resort to unconventional methods to get projects into production. That may have been compounded by the mixed reception to his recent Netflix film Fixed.

Whether a studio will eventually embrace The Black Knight remains uncertain. Still, with interest in dark, atmospheric fantasy on the rise — and projects like the rumored A24 Elden Ring adaptation potentially opening doors — there’s a clear path for an intense, animation‑driven property to find an audience. If momentum builds, Tartakovsky’s long track record of gritty, kinetic storytelling could finally propel a project to wide recognition.
