The Region 2 UK release is identical to ours, but presents the film in its original aspect ratio. It is not clear whether the soundtrack is only an isolated score. As far as I can tell, it is uncut.
The Region 1 release is also presented in its original aspect ratio with French subtitles, but no English subs. The disc has two commentaries, the same cast and crew commentary we get plus a solo effort by McKenzie. The original narration featurette is included. The disc is censored to gain an R rating. Joe and Ella's first sex scene has been trimmed, but the footage can be found as a deleted scene. Region 1 loses about three minutes, hardly an insignificant cut.
Weighing it all up, I'd call Region 2 the winner. The correct ratio tips the balance, but our uncensored disc beats out Region 1.
