Yep. Scotty's Starfleet mustache was first mooted in Filmation's quashed proposal for a TAS show featuring Scotty training "space kidettes". TAS cadets by Therin of Andor, on Flickr Mr Kyle stole it: http://en.memory-alpha.org/wiki/Kyle?file=Kyle%2C_2269.jpg
And again, improperly editing a quote backfires. Over the years I've experimented with tightening TMP as an editing exercise, and it's actually pretty easy to cut several minutes out of it with some very specific trims. Some of the easiest are just getting rid of unnecessary commands and replies in the bridge scenes.
^ It's really easy to do! Often like a Three Stooges skit involving glue, once it gets botched, it's hard to un-botch it. Best always to try to be careful to begin with.
If I can't even edit a post what hope have I of editing a movie? Ambivalent should be our word of the day. Sums up these boards nicely.
Shatner himself sported a moustache as Kirk's dead brother. See also the Earps in "Spectre of the Gun". And Anton Kiridian. And the guy in TMP wasn't even the first moustache in Starfleet...one of the tribunal in "Court Martial" had one.
The only editing that TMP needed was in the crew watching the viewscreen for ten minutes. Goldsmith's score was almost rythmically repeating, during that sequence, it wouldn't be too difficult to shorten. I would also add as much dialogue and crew intereaction as still exists and is available for use. Even Shatner's "Oh my god ..." during the transporter accident, I would keep. And no matter what, I'd be certain to keep the UFP logo, from the floor of STARFLEET COMMAND, in the shot where Kirk meets Sonak on Earth ...
