- Often debated as to how close Philip Marlow (a writer who suffers from crippling psoriasis) is to his creator Dennis Potter (a writer who suffered from crippling psoriasis). Dennis Potter denied any resemblance saying he just used psoriasis as he didn't have to research the condition.
- The notorious Moral Guardian Mary Whitehouse assumed that the programme was largely autobiographical and claimed in a radio interview that Potter had been mentally scarred as a child by seeing his mother having adulterous sex, as the young Marlow does. Potter's mother sued for libel and won.
