Copkiller fell into public domain hell in the 1990s. This led to a flood of cheap, dollar-store DVDs. These discs were often mastered from VHS tapes recorded off late-night TV. The subtitles (for English subtitles on Italian audio tracks, or vice versa) were rarely checked for quality.
The film was shot without live sound. Actors spoke in English (Keitel, Lydon) and Italian on set. The post-production dubbing created two official tracks: an all-English dub and an all-Italian dub. The problem? Most subtitle files were created by someone listening to the Italian track but typing what they thought they heard in English. The result was semantic gibberish. copkiller 1983 subtitles fixed
