Anime fans who missed the theatrical chaos—or simply want a second round—now have a date circled in red. Chainsaw Man – The Movie: Reze Arc arrives exclusively on Prime Video on Saturday, September 19, 2026, exactly one year after its cinema debut.
A theatrical monster headed to the living room
Produced by MAPPA and directed by Yoshihara Tatsuya, the film adapts Fujimoto Tatsuki’s fan-favorite Reze Arc, continuing the story that made the TV series a global phenomenon. By mid-2026 the movie had already cleared roughly 29.7 billion yen worldwide, turning a single manga arc into one of the decade’s loudest anime box-office stories.
What streamers get on day one
Prime Video’s exclusive window means no scavenger hunt across apps: the theatrical cut lands in one place, with the film’s high-voltage action, soundtrack punch (including Kenshi Yonezu’s theme work), and the Reze–Denji fireworks intact. For viewers who only know the series from weekly episodes, this is the cleanest on-ramp into the arc that many fans call the story’s emotional peak.
Why the timing clicks
September has become anime’s streaming sweet spot—blockbuster films cycle from theaters to platforms while awards season and fall TV launches keep pop culture noisy. Pairing the Reze Arc drop with that calendar gives casual viewers a low-friction entry and hardcore fans a rewatch party date. If you have been waiting for the big-screen intensity without the ticket price, September 19 is the night the chainsaw comes home.
Mark your calendar: Chainsaw Man – The Movie: Reze Arc streams exclusively on Prime Video starting September 19, 2026.
