Mr Havitol's hideout is the redressed set from "Death in Disguise", especially the hallway.
One of the very few times, if any, that the main villain, William Havitol in this case, never even met Wonder Woman. Diana Prince, yes, but not as her super heroine self. Only his goon, Dirk, got to encounter her.
The Rover sound effect is the Road Runner voice, also put out by Warner Brothers.
The one of the computer in Havitol's hideout is an AN/FSQ-7.
