Netflix Summons Wednesday Creators for Adult Animated Adaptation of BOOM!’s Grim

Netflix is officially expanding its supernatural empire, and they’re doing it with the powerhouse duo behind the streamer’s biggest English-language hit. Al Gough and Miles Millar, the creative minds who turned Wednesday into a global phenomenon, are developing an adult animated series based on Grim, the acclaimed horror-fantasy comic from BOOM! Studios’ Stephanie Phillips and Flaviano. The project is in development now, with Deadline confirming the early details and Netflix keeping everything “no comment, no confirmation” tight — which usually means the deal is real.

What makes this one pop is the combination of talent. Gough and Millar are executive producing, bringing along Millar/Gough Ink’s Aaron Schmidt, while Jennifer Yuh Nelson — one of the biggest names in animation and the Emmy-winning Supervising Director of Love, Death + Robots — is also on board as EP. BOOM! Studios’ Stephen Christy and Adam Yoelin are executive producers as well, with Mette Norkjaer co-executive producing. Phillips and Flaviano also join the series as co-EPs. For fans of the comic, that level of creator involvement matters.

And honestly, Grim is tailor-made for this format.

The series centers on Jessica Harrow, a newly recruited Reaper who guides the dead into the afterlife. Every other Reaper knows their origin story — except Jessica. She has no memory of who she was, how she died, or why she’s stuck ferrying souls. Her search for truth drags her deeper into the architecture of the afterlife itself, uncovering cosmic secrets, hidden systems of power, and a personal connection to Death that rewrites everything she thought she was. Tonally, it’s a mix of supernatural noir, cosmic horror, and the kind of myth-driven fantasy that animation can unleash without compromise.

The comic debuted in 2022 and immediately became one of the highest-selling launches in BOOM! Studios history. Its 25-issue run wraps this month, making the Netflix adaptation perfectly timed to push the mythology into a new phase. BOOM! is on a roll this year — their series Butterfly just launched on Prime Video — and Grim is one of the crown jewels of their modern catalog.

For Gough and Millar, Grim continues a long tradition of genre storytelling that blends emotional stakes with world-building. With Wednesday, Smallville, and the upcoming Beetlejuice Beetlejuice, the pair have proven themselves absolute machines at delivering stylish genre hits that connect with huge audiences. Bringing them together with Jennifer Yuh Nelson feels like Netflix strategizing their next major animated franchise.

What Grim has that gives it a real shot is identity. It’s not just another supernatural adventure — it’s a reimagining of the Reaper myth that centers a protagonist who is literally walking into the unknown, carrying the burden of death while searching for her own. If Netflix lets this team lean into the horror-fantasy tone of the comic, this could easily become one of the streamer’s flagship adult animated series.
