Revealing mistake: Higgins is explaining the story of Bannister, which he conveniently happens to know all about. In Magnum's reaction shot, you can see that he starts giggling a moment before Higgins actually gets to the amusing part (that he was specialist at posing as a female). (00:17:50)
Revealing mistake: The killer nun is making "his" escape; shoots dead one secret service guy who in the spirit of 80s network television shows not a drop of blood and is propelled through the air as if he was hit by a cannonball and not some little silenced pistol. (00:45:25)
Revealing mistake: When Magnum shoots the nun, the one who falls off is a stuntman who would pass off as Gargamel but not as Christopher Morley. (00:46:25)
