In terms of the COMPLETE version of this pilot, there is a chance it was released on a Portuguese VHS tape in about 1987. A clip of this has shown up on YouTube where it doesn’t cut from the uncut black and white footage to the color 1967 footage. I think a couple of complete shots could have also been taken from the original trailer for The Menagerie.
From what one TrekBBS user has said, the original editing was much looser and the ending in particular was very noticeable with this (the final conversation with the Talosians is said to be much more somber in the original than the Menagerie recut).
I don’t know if this Portuguese VHS has ever been ripped or not, but it would be seemingly invaluable.

My copy comes from a South American collector, not sure about the original source. But it could be this one. So any good tips for colorization? 😃
