I guess the thread title sums up the question. Only thing I would like to add is you can't pic from guest stars or even semi reacurring actors who feel like regulars such as Dukat,Nog,Barcay etc. Only exception is Dr Pulaski who wasn't officially a regular but we know she was one. My favorites would be
William Shatner as himself in "Free Enterprise." I love that movie and he does a good job of making fun of himself but also showing a serious side as well.
Walter Koeing as Bester on "Babylon 5" He did a good job as a villian and it's I think his best acting he has ever done.
Patrick Stewart as Proffesor X in "X-Men" movies. If it wasn't for Wolverine I would say he was proably the heart and soul of the entire franchise and his ending in "Logan" is just as good as Wolverine's ending in that movie.
Patrick Stewart in "Blunt Talk" It was a really funny show that can make things like Stewart having a man servant who reads him bedtime stories so he can sleep seem perfectly natural.
Brent Spiner as the scientist in "Independence Day" I fun crazy science guy is always intresting and he did a good job of making him seem like someone out of touch with society.
Avery Brooks as the teacher in "American History X" It's kind of a small role but he strikes me as a teacher who might be able to break through racism and reach a racist who had that kind of thinking basically brainwashed into him.
Nana Vistor as the dying women on "Battlestar Galatica" Not much to say but she really felt like someone who was dying and they did a good job with makeup because she looked sickly in that episode.
Colm Meaney in the movie "The Van" I kind of have forgotten alot about the movie except that he was good in it. Same with "Layer Cake"
Colm Meaney as the dad in "Get Him to the Greek" It is wierd seeing Chief O'Brien doing drugs and being a kind of asshole but I liked it.
Odo actor as Clayton Endicott the third in "Benson" It played a great sitcom villian. SO much so that I still recall him even though I proably haven't seen the show in over 20 something years.
Armin Shirreman as the Principal in "Buffy the Vampire SLayer" A slimey unlikeable guy who is kind of Quark like when you think about it.
Nicole DeBoer in "Dead Zone" She played a woman who was sweet and kind and you could feel for her that she basically had 2 men she both loved.
Nicole DeBoer in "Cube" Nerd who is trapped in a torture trap. I like how she had to overcome her fear to try and survive.
Robert Picardo as Woosley on the "Stargate" shows. Went from a typical beaurcrat to a more well rounded version of that type of character.
Robert PIcardo as Coach Cutlip on "Wonder Years" Basically played the sterotype of that job with lots of fun.
Scott Bakula as Sam from "Quantum Leap" What can you say. A great human being in a great concept for a great show.
John Billinsley as a evil scientist on "Angel" who gets what he deserves and becomes a werewolf meal.
John Billinsley on "Stargate" who plays a nerd. "Stargate" was a very nerd friendly show and he was one of them. Got to play one who was out of his deep on a dangerous mission plus was a "Star trek" fan which of course had to be a nod to his role on "Enterprise."
