These things happen. TMP featured extensive and elaborate alien makeup and costumes. Didn't see much of it at all. Far background crowd at SF HQ and then again a crowd scene on the Rec Deck. A few standout characters but nothing representative of the array of aliens they worked on. A lot of effort for comparatively little screen time.
The ultimate example is STXI's Rura Penthe scenes, which featured dozens
of elaborate aliens (including new-look Klingons, a Gorn, a Salt Vampire and a freaky guy with three faces) only to be left on the cutting room floor.
At least the new look Klingons are being reused in the next movie.
Klingons have been confirmed for JJ Trek 2013? Where is that source? And they will look like Victor Garber from the JJ Trek 09? Where is that source?
