So, one member of this thread once stated that he had seen the TVH work print, any reports on that?
I was shown the ST IV workprint at UIP's theatrette in Sydney. It was after the US premiere but before the Sydney gala preview of the theatrical release.
It had uncorrected Klingon ship FX - eg. a little square frame followed with the ship model as it performed its slingshot around the sun, complete with a guy pumping bellows to emit smoke! Similarly, the Probe moved through space surrounded by a large rectangle.
Lots of "scene missing" FX slides.
And temporary closing credits that had the actors' faces in circles, IIRC.
No "additional footage".
