Quote - Who were these other more qualified actors that applied or wanted to do SG1 but were leapfrogged over? Since you know that there are many of them and you know of their qualifications, you must know who some of them were.

Would you mind explaining the logic of your question's premise?

Quote - I guess that Robin Williams, Sir Laurence Olivier, Humphrey Bogart, Robert Dinero, Jack Nicholson, Meryl Streep, and a few dozen other superb, legendary (or at least good) but not beautiful actors must've been really lucky! ;)
It has been shown time and time again - acting has nothing to do with how beautiful you look.

I agree, acting isn't necessarily joined at the hip with looks.  But, it is obvious that actors need to be outgoing, and extroversion and beauty do tend to be correlated.

Btw, Robin Williams isn't a leading man/romantic lead, he's a comedic actor.  In any case, exceptions prove rules by the fact that they're exceptions.  Though, I do think Black's role in SG-1 suits her far better than her role in Farscape did - the former lets her personality and gift for gab shine through, and she's not a brooding/annoying misanthrope romantic lead but the comic relief; in the latter she brought nothing but her camel face to the role.

Quote - Rather, it tends to be just the opposite - the better looking, the more they should have left that person in the diner from where they were scraped.

Nonsense (btw, you contradicted yourself - first you said acting has nothing to do with beauty, then you said beauty and acting talent tend to be mutually exclusive).

Quote - If people want porn-level acting from vivacious beauties hacking well written lines, well they get what they deserve.

There's that false dichotomy again.
