 Director Peter Collinsons wife, Hazel, appeared in all his films  "for luck". In this film she appears at the Mafiosos dinner as the  blonde wife of the visiting American. She was called in the last  minute because Collinson was being sent only tall, dark Italian  models and he wanted "a short, blonde scrubber". Also, when Croker  is getting out his equipment from under the bed after he leaves  prison, he calls the ax handle "Hazel."
