Mrs. Geary is played by the real-life Jackie Geary.
The song played during the final scene is 1983s "Time After Time", by Cydni Lauper.
Adam is seen wearing a Spaceballs T-Shirt which was released in 1988.
Jackie states that Wonder Woman is from the Amazon, which isn't true. Wonder Woman is from Themyscira.
Wonder Woman is an Amazonian. The Amazons are a group of female warriors based in Greek mythology, not people who are native to the Amazon region of South America...at least as far as Wonder Woman is concerned.
