Robert Harris did the restoration of STORY OF A PATRIOT. I have a strip from one of the old VistaVision horizontal prints which is how they were presented in Williamsburg for decades. The posters for the presentation said it was in VistaVision with sound by Todd-Ao. The piece of film I have has magnetic strips on it for the six track Todd-Ao sound. Since these were purpose built theaters with curved floor to ceiling screens, it was a very impressive presentation. The restored version is in 70mm and very nice. Almost worth a trip to the colonial capital to see.All issues of Ten Commandments up until the 1989 reissue when it was blown up to 70mm were in mono. The ONLY American made VistaVision film (there are some Japanese ones like The Venus Wars) to be in stereo was Williamsburg: Story of a Patriot, which was not a regular theatrical release and used a separate 6-track magnetic soundtrack (its since been preserved on 70mm).
Remember... studios don't have the ability to create 70mm blow-ups until 1963!
