The trailer was edited a number of years ago (Hence the low quality) it was a response to the official trailer for the US market, which marketed 'Leon' as some kind of Hollywood action/thriller.
The edit took about half a day and was intended more as a TV trailer (For UK youtube watchers I imagined a brief for 'Film4') which goes someway to explain the choice of music.
