Emmy-winning supervising stunt coordinator and 2nd unit director John Koyama — “Koy” on set — sat down for a new video interview about coordinating the ultra-violent, practical action of Prime Video’s The Boys and its spinoff Gen V. With 130-plus credits behind him (Twisters, Furious 7, Man of Steel, Pirates of the Caribbean: On Stranger Tides, Zack Snyder’s Rebel Moon), Koyama walks through how he keeps the show’s gore-heavy set pieces grounded and repeatable — the planning, the rehearsal and the safety work that let a Supe fight read as brutal without turning into a pure VFX handoff. He also offers concrete advice for performers trying to break into the stunt field. Fresh off two Emmy wins for the series, he’s in the running for a third nomination for the final season.
