|Diving Bell and the Butterfly, The (Scaphandre et le papillon, Le)||R1|
I will compare this R4 edition of The Diving Bell and The Butterfly with the R1 edition released by Buena Vista Home Entertainment in April 2008.
Apart from the original French audio track, the R1 edition also has dubbed English and Spanish audio tracks - all are reportedly Dolby 5.1 mixes. It also features the additional subtitles of English for the hearing impaired, Spanish and French. The extras are identical on both editions, but the R1 version sports the addition of "Charlie Rose interviews Julian Schnabel" (20:44).
All in all, the R1 edition probably edges out the R4 in terms of overall presentation.
