Other mistake: Gregory Peck and David Warner are attacked in the cemetery by four large vicious dogs, who attack their throats, arms and legs, but once they escape, the only wound seen is the one on Gregory Peck who hurt his arm while climbing over the fence.
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)
Other mistake: Rita is only hit in the thighs with the basketball rafter. That couldn't kill her, and it couldn't make blood come out of her mouth.
