Directed by: Gerald Thomas
Starring: Kenneth Williams, Sid James, Charles Hawtrey, Sidney James, Jim Dale
Revealing mistake: When Sir Rodney leaps from the banister onto the chandelier during the fight at Chateau Neuf, it is not Sid James but a stunt double.
Revealing mistake: When the first fingernail drawing is attached to the guillotine with the knife, you can see the wire that was used to guide the knife attached to the end of it.
Visible crew/equipment: When Charles Hawtrey "jumps" onto the light near the end of the film you can see the strings pulling him across. The same can be seen with Jim Dale as well.
Lady Binder: But then, you've always had magnificent balls, and I wouldn't miss one of them.
The Black Fingernail: Thank you Lady Binder.
