The same newspaper blurb about Harvie's lighting strike is re-used for the blurb about his magnetism.
The deaths of Harvie's parents - which occurred during the invasion of Poland by Nazi Germany - should have taken place in 1939, not 1942 as indicated by their gravestone.
Harvie's 65th birthday - and Val's death - should take place in 1987, in accordance with the title card indicating that Harvie was born in 1922, but Val's gravestone states that she died in 1984.
