Someone asked if Arex and M'Ress would be in the movie. GR doubted it would be possible, at that time, to do a believable, live-action Arex but... that he'd tried to cajole Majel Barrett into taking two roles in the movie: as Dr Chapel and M'Ress! Majel was steadfast in her refusal to consider trying to act under the required prosthetics.
Certainly, at that point, GR had no major problems with integrating TAS into future ST.
Wow, I'd love to see someone attempt to do Arex and M'Ress in a live action Trek production! Abrams, are you listening?
