Mission Impossible has three sucessive long-term female team members (Cinnamon, Casey and Dana) but a number of actreesses also guest starred in one or more episodes. This happened particularly after Barbara Bain’s abrupt departure and during Linda Day George’s maternity leave.
Jessica Walter went undercover as Valerie in the single episode ‘Orpheus’ in the fourth series between Cinnamon (Barbara Bain) and Casey (Linda Day George).
