Bizarrely, the Region 1 version has a fairly different set of extras and other features compared to our local version. The extra things on the Region 1 release include
- A third disc for the extras
- A Dolby Digital 5.1 soundtrack (which sounds like it would be significantly preferable to the local 2.0).
- Commentaries on two episodes
- A 15 minute making of called 'A 6 hour film shot in 92 Days'
- A 16 minute featurette about the story called 'Beautiful Prison'
The Region 4 version has some things not contained on the Region1 version which are
- The full cast interviews - only a cut down version of the McKellen one appears on Region 1
- Inside the Prisoner (although this may be similar in content to the two extra ones on the Region 1
- The read-through featurette
- The Special effects featurette
On balance, the Region 1 sounds like the best choice due to the 5.1 soundtrack and the commentaries especially.
