This was the first episode to be fully scripted, previously the actors just ad-libbed.
Tom Servo walks into the theater after the first break. Normally he is carried by Joel. He makes an allusion in the next break to the fact that he likes being carried into the theater and he would be for the rest of the series.
From this point on, every movie was used with permission.
The first episode of the series to be aired on national television.
This is the first and only time that Joel opens the outside theater doors by hand.
