How is it possible to have a technicolor print if the film was not shot on 3 strip technicolor…??
It can still be printed on 3 strip technicolor even if it wasn’t shot that way. Same as how you can have a 35mm film printed onto 70mm stock.
JEDIT: Or at least it could if Technicolor was still doing these kinds of prints, but Star Wars was actually the last movie they used this process for before shutting down their labs.
