I'm currently working on a film restoration project for a French film archive. We have the Super Technirama negatives to a french film made in Brazil in the 1960s, that we're considering to blow up to a 70mm release print.
To be precise, the film was shot on 8-perf/35mm horizontal VistaVision style with a 1.5x anamorphic squeeze. This was intended to be blown up to 5-perf/70mm release prints.
This is the film: https://www.imdb.com/title/tt0353979/
We're not sure if the producer ever managed to make any 70mm release prints. We know that the film was shown originally in Brazil but that may be 35mm prints, we don't have any surviving copies of that. He had originally intended to release it on 70mm in France but he ran out of finances before he could. He had managed to get a visa d'exploitation in France though.
I had approahced FotoKem in Los Angeles and they said they do not have the possibility to do a un-squeeze on the 8/35mm negative to print to a 5/65mm inter-negative. They've suggested a 4K digital interneg to 70mm filmout but I really don't see a point in that.
Anybody here knows any labs and/or technicians, restoration experts who could do this? Basically we need to do a 1.5x un-squeeze from a 8/35mm to a 5/65mm.
I feel like this is a longshot, as the archive will probably eventually just go with a 4K restoration DCP but if I can find a way to achieve a 70mm filmout and a price quote to present our financers, this could happen.
Also, can anyone confirm if this is the first French film shot for an intended 70mm release?
Jacques Tati's Playtime (1967) is the only french 70mm film I know and this film predates it by a good three years.
Thanks in advance for responses!
