Allen is perhaps best known on TV for her role as the creepy saleslady in the first-season episode of Rod Serling's original version of "The Twilight Zone", entitled "The After Hours", where actress Anne Francis (playing 'Miss Marsha White') finally realizes that she is a mannequin and that her month of freedom and living among the humans is over. Allen's saleslady character (seen by no one but Marsha) is the mannequin whose turn in the outside world is up next and has already been delayed by one full day, thus explaining her slightly peeved attitude.
