EaglesWing, what I meant is that the hero (I forget the name of the character) may well not be able to do a thoroughly convincing authentic accent--and indeed, given the comic nature of the movie and the situation, it is perhaps better that the accent is not 100% accurate.

If Robin Williams were actually impersonating an authentic Scotswoman, then one could expect a fine approximation of a Scots accent. But he's impersonating an American who is impersonating such a woman. I believe there's a big difference.
