There seems to have been nigh-on two decade's of speculation about the pseudonymous identity of Natalie's abuser in this film - but if you know where to look, it is easy to find something: Take the letters of Kirk Douglas's personal favourite of his own films - Lonely Are The Brave - discard a few, and rearrange the remainder, and you have ... 'I'm Roy Treane' (the 'I'm' being the absent two letters from 'Tremaine').
