I can confirm that the main feature does indeed have English subtitles. The extras do not. There are also French subtitles for the hard-of-hearing, which frankly covers everyone trying to listen to the film’s murky soundtrack.
As far as I can tell, the version of the film itself is the same as that presented on the old Gaumont DVD, the different runtime explained by the latter’s PAL speedup. When the Blu-ray was first announced, one of the extras “TBC” was an alternative print of LA FIN DU MONDE – presumably the shorter copy held in the Národní Filmovy Archiv, Prague. This has not been included, which is a shame. But what the Blu-ray really needs is a summary of Gance’s original scenario and/or screenplay, complete with any available production stills to help fill in the gaps. Gance assembled an initial print of 5250m (about 190 minutes), whereas the version released in cinemas was 2800m (about 101 minutes). Gaumont’s print is 95 minutes long, so not even as long as the latter.
The inclusion of AUTOUR DE LA FIN DU MONDE (1931) is a welcome extra on the Blu-ray, as its only previous release was as part of a compilation DVD some years ago in an issue of the French journal 1895
. As a “documentary” record of the production, it is less coherent than the feature film itself – offering random scraps of behind-the-scenes footage, test shots, and cut scenes. But it is worth watching for one shot alone: the close-up of Antonin Artaud screaming into camera, with hallucinatory lights behind him and a warping effect in front of the lens. It's just about the most astonishing close-up Gance ever filmed. A glimpse of genius amid the mournful wreckage of LA FIN DU MONDE.
