Legends and Magic: Warner Bros. Animation Unveils Genndy Tartakovsky’s ‘Conan,’ New ‘Adventure Time’ Spin-Off, and More

Posted on by

Warner Bros. Animation and Cartoon Network Studios brought major firepower to the Annecy International Animation Film Festival, packing their joint studio spotlight panel with monumental project announcements. The presentation leaned heavily into a mix of deeply coveted passion projects from industry icons and highly anticipated expansions of modern animation classics.

Genndy Tartakovsky’s Dream Project: ‘Conan the Barbarian’

In a massive announcement that electrified the crowd, animation pioneer Genndy Tartakovsky revealed he is finally bringing Conan the Barbarian to life. Partnering with Cartoon Network Studios and Prime Video, Tartakovsky is helm-directing an animated series based on the legendary Robert E. Howard character—a project he has been actively pitching since 2008.

“The world wasn’t ready,” Tartakovsky shared via a video message at the panel. “But now, after adult Samurai Jack and Primal, it is prime—not just Prime Video, but prime for this story to come to the screen.”

While no finished footage was screened, the studio unveiled the first official teaser poster, showcasing the titular barbarian rendered in Tartakovsky’s unmistakable, sharp-edged, high-action visual signature. The project marks the filmmaker’s first foray into a pre-existing, third-party property since his groundbreaking 2003 Star Wars: Clone Wars micro-series.

Returning to Ooo: ‘Bubblegum and Marceline’

The beloved Adventure Time universe continues to expand. Showrunner Adam Muto and the creative team behind the acclaimed Fionna and Cake series are returning for an all-new spin-off titled simply Bubblegum and Marceline.

The upcoming series focuses entirely on the deeply layered, fan-favorite relationship between Princess Bubblegum and Marceline the Vampire Queen. The confirmation serves as a massive milestone for the franchise, proving that the vibrant, lore-heavy world of Ooo still holds plenty of stories to explore eight years after the original flagship series concluded its historic run.

First Looks: ‘SuperMutant Magic Academy’ and Beyond

The studio spotlight also offered extensive looks at major episodic projects currently moving through the production pipeline, highlighting a strong push toward diverse visual styles and genres:

  • SuperMutant Magic Academy: Heading toward an upcoming premiere on Adult Swim, the studio debuted the first footage of this highly unique adaptation of Jillian Tamaki’s celebrated 2015 comic. The series delivers a sharp, witty blend of teenage slice-of-life comedy and high-fantasy surrealism, tracking the relationship drama, high school cliques, and supernatural gossip of a student body comprised of mutants, dragons, and witches.

  • Expanding the Slate: Additional development updates during the panel emphasized the studios’ ongoing collaboration with global creators to refresh legacy intellectual properties while establishing original storytelling blocks tailored directly for modern broadcast and streaming landscapes.
