Unfortunately, it seems a bootleg version of the entire film was—however briefly—uploaded to Amazon Prime.
Indie film One Cut of the Dead (released in Japan as Don’t Stop Shooting! or KameTome) was filmed in eight days after writer/director Shinichiro Ueda attended a drama seminar in Tokyo.
People who ordered ahead for the DVD/Blu-Ray may simply cancel their orders and opt for the erroneous Prime release.
