Gigant anime movie announced at Cannes

At a press conference during the Cannes Film Festival, K2 Pictures confirmed it will produce an anime movie based on Hiroya Oku’s Gigant. The K2 Pictures Cannes announcement arrived on Sunday in France, formalizing the project. The company positioned the film as an official in-house effort, not a tentative development note, which clarifies its production intent.

This move marks K2 Pictures’ first venture into animation production, a milestone stated on stage. The Gigant adaptation expands K2’s portfolio into anime features after live-action work. No teaser, poster, or website accompanied the reveal on stage, so the announcement focused squarely on the property and format.

Only the title, format, and the company’s involvement were stated publicly during the briefing. The team did not share creative attachments or distribution targets for the Gigant anime movie. Official updates are expected to route through K2’s channels once production steps can be talked about.

What Gigant is about and who Hiroya Oku is

Rei Yokoyamada, a high school filmmaker, scrubs slanderous flyers from his neighborhood and meets adult performer Papico. A bizarre incident soon grants her the power to grow to giant size. That conceit anchors the Gigant synopsis, blending human-scale drama with outlandish spectacle inside a modern Tokyo setting.

Oku launched the sci-fi seinen series in Big Comic Superior in December 2017. Shogakukan released the tenth and final volume in December 2021, setting the Gigant volumes count at ten. 2 million copies in circulation.

Seven Seas licensed it in English in July 2019 and published volume ten in December 2022.

Hiroya Oku, known for Gantz, often pairs speculative ideas with everyday characters and tech-inflected anxieties. That mix helps his stories move between intimate stakes and large-scale consequences. The Gigant manga provides that foundation, giving an anime film clear visual hooks without losing its grounded relationship core.
