Adult Swim greenlights Genndy Tartakovsky animated series “Heist Brothers,” debuting from Annecy presentation

Adult Swim has greenlit Genndy Tartakovsky’s newly announced animated series, titled “Heist Brothers,” according to an exclusive report from Deadline published June 26. The project, previously described as in development, traces back to a 2024 pitch by Tartakovsky that was presented live on stage at the Annecy animation festival.

Deadline reported that Tartakovsky pitched the concept to the President of Adult Swim during that 2024 Annecy presentation. The update comes after earlier coverage, which said a show called “Heist Safari” had been in development.

In June 2026, Deadline said the series has moved from development to being greenlit, with the creator’s new project now carrying the title “Heist Brothers.” The report describes the show as “high-octane animated,” framing it as an action-oriented concept that fits the Adult Swim brand and Tartakovsky’s established style of fast-moving, high-energy animation.

Deadline’s account also places the announcement within a broader festival timeline, noting that the 2024 pitch happened live at Annecy and that subsequent reporting had kept track of its progress. In its latest update, Deadline states that the series is effectively being carried forward by Adult Swim from that initial pitching moment into the next phase of production planning.

While Deadline does not provide full production details in the excerpted material accompanying its report, it identifies the creators and venue involved in bringing the project to Adult Swim’s slate. Tartakovsky is best known for “Dexter’s Laboratory,” and the new series represents another collaboration of sorts between a major animation creator and Adult Swim, a programming block that has built its audience around adult-skewing animated series.

The report describes the project’s evolution in stages: initial on-stage pitching at Annecy in 2024, earlier reporting on a related working title and development status, and now a confirmed greenlight and updated title for the Adult Swim series. That progression is typical of animation development, where projects can change names and packaging as they move between concept, approvals, and production.

No premiere date, cast list, or episode count was included in the information provided in the Deadline report. As production planning continues, Adult Swim and Tartakovsky’s team will be expected to provide additional scheduling and creative details through later announcements.

For viewers and families following Adult Swim’s programming changes, the greenlight indicates a near-term addition to the network’s animated lineup, while also continuing the creator-driven approach that has long characterized the Adult Swim ecosystem. For industry watchers, the Annecy-to-network pipeline highlighted in the report underscores how major animation festivals can function as deal-making platforms as well as creative showcases.
