Also, Anchorhead: Yeah, I have to admit I have always had a crush on Marcia. She was and is very cute. Aside from her physical features, I think her fiery temperment "no bullshit" independent personality was the groundwork for both Marion and Princess Leia. The most important person in Lucas' life was a beautiful but take-no-prisoners professional that one-upped her male counterparts. It's no suprise that all the women in his films at the time mimic her personality and in some sense her physical features. Karen Allen bears a vague resemblance to her and isn't so far removed in spirit at least.
