I always cringe when I see the footage of Bujold as Janeway. She didn't seem to put in any effort at all during her brief performance. She'd almost signed it off before the cameras started to roll. I'm glad Mulgrew was the next choice, she gave a more passionate performance.
What I find more interesting, is that initially, Janeway was going to be male! And, being from the UK, I was even more surprised to hear that Nigel Havers (below) had auditioned for the role!!!
I'd pay good money to see the smooth-talking Nigel having a debate with the borg queen on the viewscreen!
