The Loneliness of the Long Distance Runner was the second film that Susan Foreman and Gillian Roberts saw on 30 March 1963. It featured Tom Courtenay. With Courtenay reminding the duo of their classmate John Brent and their lack of determination to see it in the first place, they quickly left the picture. (PROSE: Time and Relative)
Behind the scenes
What's surprisingly not mentioned in the book is that — like their first film of the day, Saturday Night and Sunday Morning — The Loneliness of the Long Distance Runner is based on a novel by Harry Sillitoe.
