The film exists in two (known, reported) versions. The first is the uncut 125min European version widely seen today. However, an alternate version with mostly different takes, and in which most performers delivered their lines in [phonetic] English before being (a bit ironically, perhaps) looped over by American voice actors. (A practice not entirely uncommon throughout the '60s and '70s, particularly with French cinema). The alternate English-language version runs 93 minutes, omitting several scenes and characters in the process; it also features different music in some places.
