Re: They really should have found a way to get Shatner on one of the m
Well of course they can still get Shatner to appear in the next film if they wanted to (as an older version of this Kirk). As for Nimoy's cameo in STID I think the film didn't really need it. They had passed the torch in Star Trek (2009)
On the continent of wild endeavour in the mountains of solace and solitude there stood the citadel of the time lords, the oldest and most mighty race in the universe looking down on the galaxies below sworn never to interfere only to watch.
