"The filming of one scene in particular is extremely difficult for me to recount. Daphne asks a question to which Doctor Lawrence replies 'my wife is dead...' The tone of utter finality in his voice was absolute. At this point Doctor Lawrence picked up a photograph of his late wife - in actual fact Peter had insisted on using a picture of Helen. This scene was shot about seven times, and each time Peter uttered that awful sentence he became more broken. Finally tears streaking down his face, he swiftly walked off the set. Freddie Francis simply turned and looked at the floor amid the horrible silence."
