I would like to further explain my entry, if I may. It's Geroge Takei on ITV's I'm a Celebrity, Get Me Out of Here! reality game show in 2008, and then. The other two are from that Sharp Quattron advert/commercial.
Ok, so say an actor made an appearance as a character on a TV show before their final appearance in Star Trek, but made subsequent appearances on that same TV show after their final appearance on Star Trek. Would anything from those subsequent episodes be permissible, or would it be disqualified as the first appearance as that character was before they last appeared on Trek. Yes, I do have someone specific in mind.
And oh crap, something else just occurred to me. Are we talking strictly canonical Trek, or would doing a voice in a video game count, or appearing in a fan film count as a Trek appearance?
I think this will be my entry - Michael Dorn, Nichelle Nichols, George Takei, Erick Avari (and Zachary Quinto), Thomas Dekker, John Glover, Dominic Keating & Malcolm McDowell on Heroes
A quick check of IMDB says he was in two episodes of Voyager, and one of the little kids in ST: Generations. I would never have known that.
oh, he was Lord Burleigh's son... i suddeny decided to check my encyclopaedia at lunchtime (PC was off) and saw he was one of Picard's kids in GEN.
Hmmmm.... I would've thought something Trek-centric would've gotten more entries. Poll goes up Monday.
^ Well, if ya think about it, most of the main TOS cast didn't do much actin' after the sixth movie. With TNG, Jonathan Frakes switched over to direct more than act, as has LeVar Burton, while Gates McFadden has only three or four credits post NEM. Brent Spiner has done a few guest spots here & there, but his ENT appearances happen after NEM, puttin' the possible entries for him back another year or so. And his best non-Trek role will always be Bob Wheeler on Night Court. DS9's cast skewed older, and Brooks, Visitor & Auberjonois mostly stick to stage productions, it seems, though I will admit I'm surprised no one went with Kasidy Yates from 24 or even Bashir from Syriana. And from VOY's cast, Dawson & McNeil direct more than act these days, and Robert Picardo's best roles were pre-VOY, not post (thought Woolsey on SGA could work). And while Bakula will always be awesome, in my book, for Quantum Leap, I'd say Trinneer has been the most prolific since the series ended, and JiNX has him covered with her entry.
Picardo appeared in a couple of episodes of Castle (season one) and he was also on the Stargate shows. Dr. Clark Murray (Castle) if anyone wants to enter this, help yerself!
