Hey, wouldn’t it be much more easy to make a reconstruction like Harmy did with his despecialized trilogy? Use the official Blu Ray version as a main source, combined with elements from a late HDTV broadcast of the 2001 DVD Version and some upscales from the Japanese Laserdisc?
Easier? Probably not.
Cheaper? For sure.
But that’s missing the entire point of scanning 35mm reels.
Not to mention the fact that the Blu Ray master completely destroys any detail the film stock had.
