|L' Appartement (The Apartment) (Madman Ent)||R2F|
There appears to be no R1 release.
The R2 French release has a 5.1 Dolby Digital Surround soundtrack and a 5.1 DTS soundtrack available, as well as two extras – The Movie In 100 Photos and Test Screening: Cruelle Melopee.
The R2 UK Release appears identical to the R4 release except it is not 16x9 enhanced.
Obviously, the R2 French release is the way to go for serious fans of this movie, but for its cost effectiveness the R4 is still a good buy.
