It was published by Victor Gollancz Ltd.. Irvine stated she longed for a “major personal challenge”. She also acknowledged she was taking chances, but as she was neither in a relationship nor had children, she felt it was worth taking. Her book was the basis of the 1986 film Castaway, starring Oliver Reed as Gerald Kingsland and Amanda Donohoe as Irvine.
