Although they similarly began their acting careers at very young ages and enjoyed great success in acting, this is the only time Sal Mineo and Patty Duke appeared together.
Although he appears as himself and suggests that he went to high school in Brooklyn, Sal Mineo was actually born in the Bronx. His formal education was cut short when he was expelled from a parochial grammar school and, after trouble with the law, given the choice of reform school or acting lessons. He, of course, chose acting lessons.
This is the first of four credited appearances Kelly Wood makes in the series, each time playing Patty's high school friend Gloria.
