This episode is dedicated to Jean Smart's late husband, Richard Gilliland, who died towards the end of production. Ironically, a large portion of the episode is set at a funeral.
The scene outside the convention centre is not the Las Vegas Convention Center, but rather The Long Beach Convention Center. Signs for Bay Street although out of focus can be seen in the background in a few shots
When Ava travels to Boston to visit her mother, there is a 5-second scene-setting aerial shot of the landmark "CITGO" sign in Kenmore square. This is followed by a 5-second clip of a bus showing a destination of "BOSTON". The bus clip was taken in Vancouver, BC, looking southeast on W. Cordova Street. That particular clip was also shown on the ABC mini-series, "Madoff" back in 2016.
