“STAR TREK - When Original Series Characters Appeared Outside the Original Series”

This would include:

Encounter at Farpoint (tv movie version) w/ McCoy
Sarek w/ Sarek (duh)
Unification I and II w/ Spock
Relics w/ Scotty
Blood Oath w/ Kang, Kor and Koloth
(and I’m skipping Kor’s other appearances even though John Colicos was ace)
Trials and Tribble-ations w/ most of the TOS cast
Flashback w/ Sulu and Rand
In a Mirror Darkly, parts 1 and 2, which I know doesn’t have any original cast members in it but its close enough

I’m not sure I would include Generations, despite it having Koenig, Doohan, and Shatner as Kirk, since its such a horribly shitty movie.

But either way, that’s a box set I’d buy.
