Yes, Miramax was said to be restoring these more than 18 months ago but I have been unable to find out anything since. The work was supposed to have been carried out on 'Empire' and 'Circus World' as well as 'El Cid' and '55 Days at Peking'.
I started a similar thread to this some months ago when a very helpful HTF member told me about some Region 2 releases of these movies. Some have forced subtitles. However, the German releases do not, so I took the plunge and ordered all of the above from Amazon.de (except 'Circus World' although that's available too).
On each of them you can select the original English dialogue. The only extras are star biographies and trailers although these are all in German. They are in 2.25:1 widescreen (which I know doesn't exactly match the original Panavision 70 ratio) and in Dolby - BUT, the packaging says, in mono. Yet 'Empire' sounds like stereo to me.
Purists may want to wait for the Miramax releases but I'm well satisfied and they are all certainly streets ahead of the pan and scan VHS and DVD efforts that have limped onto the market before now (well, in the UK anyway).
Of course, it depends if you can play Region 2. But I think you should try maybe one and see.
I have the French DVDs of "Fall of the Roman Empire" and "El Cid" both of which are anamorphic widescreen and stereo, although like the German versions the packaging states mono. Quality is very good but what I want are restored roadshow versions with Overture, Intermission etc. These four Samuel Bronston epics are top of my "wants" list, so Miramax...PLEASE GET A MOVE ON AND RELEASE THEM!
I would go with the German releases as these don't have forced subtitles. I have the French releases myself and they're nice but like Douglas I can't wait until these will be released in their full roadshow glory.
