I don't think the Jedi bootleg is a 70mm recording, is it? And the 35mm mix is already on the V3.

I don't know, to be honest. But I think it's just a regular 35mm anamorphic print. Here's why:

The Jedi taping seems to be from a private screening, as there are no crowd noises etc. Also, the projectionist has obliged by switching from anamorphic to flat lenses on the fly, keeping the opening crawl and the end credits squeezed to accomodate the camcording. I am not familiar with cinema projection, but would such a thing be possible with 70mm projectors? Do they even have flat lenses?

Furthermore, we know this screening is of a UK print (The UK certificate at the beginning). Were there any 70mm prints shown in England?
