Goof: The saddle of Ookla's horse is missing when he takes it with him into Crom's fortress, but it eventually reappears.
Goof: When Ookla sits on the recliner at Samantha's house, it was a light shade of blue. But when he gets up after turning on the TV, it's more of a light shade of green.
(After seeing Thundarr defeating Crom's metal monster after he and the group arrive in old Earth leading to all the commotion)
Police Officer: Wizards, barbarians, monsters?!? This can't be real! (Ookla taps him on the shoulder so he can get the horses) Sure, buddy. It's all yours. Happy trails!
(After seeing Thundarr cut through a wall with his sunsword)
Samantha: Boy! I'll bet that sword can chop up a battleship.
Ariel: It has.
This episode is set in the ruins of San Antonio, Texas, in the vicinity of the Alamo.
This is a rare episode in which Thundarr doesn't use his sunsword in the climactic battle scene.
