In the scene where Sam is quickly trying to leave the living room to go find Suzi, you can clearly see that Scott Bakula is wearing modern-day tennis shoes instead of heels.
Eric Bruskotter, who plays the heckler "Red," also appeared in the Season Four episode "Raped" as Glen, and in the Season Five episode "Memphis Melody" as Beau, who is beating up Elvis.
Although it is set in 1968 there are at least two scenes that show cars from the 80s. The most obvious one is when Diana is driving with Suzi to the sit-in under the Shawmut sign that I also remember from the 80s. There is a mini van driving behind her 60s Volkswagen Van.
The other one was when Suzi went to Diana's office and her mom went to pick her up, when Sam is driving the car and the scene is looking from the front out the back window of the car all the cars on the street are older model cars from the 50s and 60s then they do a scene from the outside showing Sam driving off and you can see except for the Volkswagen beetle on the left the other cars on the right are late model cars although you can't quite tell what they are.
This fifth-season episode was featured as a bonus on the 4th Season DVD box set.
This is one of the most radical episodes in the entire series. Not only does it support the Equal Rights Amendment but it also offers brief support of black liberation, gay liberation, and a single payer health care system.
When Sam is in the kitchen with his "son", the boy says he does not want to miss The Flying Nun.
The Flying Nun was a television series starring Sally Field as, quite fittingly, a nun who could fly. The series ran from 1967 to 1970.
In this episode, Suzi refers to Sam Beckett as "the famous playwright," one of the many references throughout the series to Sam's name being similar to the Noble Peace Prize winner.
