Other mistake: Legendary wrestler Antonino Rocca makes a cameo appearance in the movie. He is, as correctly listed in the closing credits, one of the "Funeral Attendants" together with Michael Weil. However in the opening credits he was specifically billed as the Funeral Director, which is Ronald Willoughby's role as correctly listed in the end credits. (00:00:50 - 01:45:15)
Revealing mistake: After the arrest of her fake father, Annie Belle reaches Linda by phone. Naturally, she is swimming in the nude. Linda then turns to her husband, who is just then reading about Michael's arrest. The headline about this Hong Kong arrest is a glued-on slip of paper on top of an article set in Lyon. (00:21:30)
