Justin the school janitor (aka Shining Knight) is shown in his janitor's closet touching a calendar page of a horse most likely as an homage to his flying horse Winged Victory. Soon after his sword is shown in a mop bucket.
Lea Thompson directed this episode. She previously starred in the classic film, Back to the Future. To honor that, the crew built a replica of Roy's Records one of the shops seen in the classic Robert Zemeckis film.
Yvette Monreal greatly enjoyed working with Lea Thompson stating: "I love Lea so much. She was one of my favorite directors. I loved that she was an actress and now she's directing, so she just really knows how to speak to us actors. If we're not getting something right, it's nothing too general. Some directors tend to say, "Hey, do that more mad," or "Do that more happy." She gets into it and she speaks to us in a way where we can really understand the final product that she wants and actually execute it. She speaks to us in a way where we all could understand. She was amazing. I hope that we can have her again because she was literally the best. She was my favorite, favorite. The episode was awesome, too. The fight scene was incredible."
While Pat is leading the Justice Society to his bargain-basement training simulator, a familiar green car can be seen in the background. The vehicle is a dead ringer for the one Superman is holding on the cover of Action Comics #1, and next to the Batmobile, it's probably the most famous car in the DC Universe.
The original male Fiddler is briefly glimpsed as Pat tells the new JSA about their opponents.
