I know AM was pregnant and they released her from her contract, but surely they knew her departure date and could have auditioned a few more appropriate actresses for her replacement.
For me, the problem with Betsy Durkin is her voice. It's so shrill! Vicki had a refined, cultured-sounding voice, soft and nice. This choice might have been made in haste, but there was really no reason for it.
Joanna Going, who potrayed Vicki in the 1991 series remake would have been wonderful, but probably not born yet. And I think Kate Jackson, who joined the show later, would have been a decent replacement for Moltke, but she was still in acting school then.
It's a pity. Vicki's was a pivotal role and they used Durkin, a huge mistake to big fans of the original actress.
