The premise
Attack of the Samurai Sharks (2026)
A 3,000-year-old cold case could be the earliest known victim of a shark attack. The skeleton, found in Japan, is covered in unusually deep cut marks. It looks like the victim of a frenzied samurai sword attack, but could his wounds have been caused by a shark? If so, which species of shark is the prime suspect? Shark experts Alyssa White, Gavin Naylor, Kirin Sekito and Masato Nakatsukasa investigate.
Opening against The Odyssey, this one will be fighting for the same weekend conversation.
Attack of the Samurai Sharks arrives on streaming July 6, 2026.
