The scene on the evening before the record attempt, we see Donald Campbell picking up the phone and calling his wife. This was not correct. In fact, it was his wife who telephoned him. First she tried (through the operator) to reach him at the hotel, but he was not there. He was in the boathouse. So the operator connects her there. However, before the operator puts her through, he wishes Donald "good luck"for tomorrow.
When we see Sarah Williamson's report on Donald Campbell in her typewriter, it refers to Consiton as a "Cumbrian village". In 1966 Coniston was in Lancashire. It did not become part of the newly created county of Cumbria until 1974.
