 The final scene of the film, showing Laura embracing her husband after he shows that he has noticed her distance in the past few weeks and perhaps even guessed the reason, is not in the original Coward play.There are two editions of Coward's original screenplay for the film adaptation, both listed in the bibliography.Much of the film version was shot at Carnforth railway station in Lancashire, then a junction on the London, Midland and Scottish Railway.
