 In the film, Laura has only just arrived at Dr Lynn's flat when the owner returns and is immediately led out by Dr Harvey via the kitchen service door.Later, when Laura seems to want to throw herself in front of an express train, the film makes the intention clearer by means of voice-over narration.Also, in the play, the characters at the Milford station — Mrs Baggot, Mr Godby, Beryl and Stanley — are very much aware of the growing relationship between Laura and Alec, and sometimes mention it in an offhand manner; whereas in the film, they barely take any notice of them or what they are doing.
