Trivia: Actor Vic Morrow used a non-firing wooden replica of a Tompson submachine gun due to its lighter weight, thus being easier to carry. He used a heavier blank-firing model when it was required to be fired.
Trivia: In "Carry On Screaming", Harry H. Corbett is seen in his role as Inspector Bung driving a horse and cart to the tv theme of "Steptoe". A nice touch. Wilfred Brambell also had a small role in another "Carry On",where he couldn't keep his hands off a pretty young nurse.
Trivia: At the beginning of the episode when Venus is telling the story to Jonathan in his room, look at the bookcase behind him and you can see a "Supercar" book, which was Gerry Anderson's previous show.
