I think someone mentioned the Star Trek: TNG part already. It was in the second season episode 'Pen Pals', where she played an alien with really long fingers. It was on the week before 'Q, Who?', which was the first episode to have the Borg in it.
And speaking of Cyborgs, remembering Nikki Coc from T2, and then seeing T3 made me think. In T3, John Connor and Clare Danes (can't remember her character name) are talking about how when they were young they had a kiss together, so I was thinking it might have been better having Nikki Cox in the role rather than Clare Danes, becuase it shows better continuity. Besides, it isn't like taking a risk, actress-wise, because people would flock to se T3 no matter who was in it (as long as Arnie was there!). After all, they created a cheesy cameo for Dr Silverman in T3! And one last point, having Nikki Cox in some skimpy top in T3 would probably have ensured that the U.S. box office receipts would have gone beyond T2!
P.S. Imagine being holed upm in a nuclear bunker with Nikki Cox for 15 years! hmmm....
