In this era of globalization the very attitude toward the audiovisual translation (AVT) changes, subtitling has become a growingly popular method that aggravates the culturological problems of AVT of art films. The problem of rendering substandard vocabulary and obscene words remains one of the most acute problems of translation. This problem is considered by studying  Eric Rochant’s Mobius (2013, France) which is interesting not only because French actors speak Russian and Russian actors speak French, but also for high percentage of obscene words, whose pragmatic effect differs considerably in oral speech and in subtitles.
