Based on a true story, the movie was a thinly disguised account of screenwriter Terence Rattigan's life friend Vivien Leigh and her attempt to leave her husband Laurence Olivier for Australian actor Peter Finch . Leigh and Finch made it to the London airport, but their plane was delayed by incoming fog giving Olivier time to confront the two and bring Leigh home. Leigh abandoned the plan after hours of fog delay.
First film of Brook Williams.
