This is the first live-action appearance of both Sportsmaster and Tigress in full costume.
The town's Dallas Theater is playing a movie, 'Strange Adventures'. "Strange Adventures" is the name of a DC comic that was first published in 1950. Primarily a s.f. anthology, it features characters such as Space Cabbie, Animal Man, Enchantress, Deadman, and Adam Strange.
An iconic moment where the Justice Society of America is suited up together and fighting for the first time, is seen. A snippet of it was shown months ago in the eleven-second cameo on DC's Legends of Tomorrow during the Crisis on Infinite Earths crossover. However, this episode fleshes out that moment in more perspective.
Most of the scene between Courtney and Pat at the end of the episode was improvised by Brec Bassinger and Luke Wilson.
The creation of the Sportsmaster Suit was a long one, and Neil Hopkins had to try on several versions of it as they developed it. But it is apparently very comfortable to wear.
