 Such dubbing is ubiquitous in Russian-speaking countries on films shown on cable television and sold on video, especially illegal copies, and are sometimes included as additional audio tracks on DVDs sold in the region, along with dubbing performed by multiple actors.During the early years of the Brezhnev era, when availability of foreign films was severely restricted, Goskino, the USSR State Committee for Cinematography, held closed-door screenings of many Western films, open mainly to workers in the film industry, politicians, and other members of the elite.Those screenings were interpreted simultaneously by interpreters who specialised in films, where an effective conveyance of humour, idioms, and other subtleties of speech were required.
