Theres little to usefully add to the description here after watching the film again, other than to say that you also get a good scene where a young Frankie Howerd, playing a barrow boy, interacts with a cart horse intent on eating his fruit and veg, Mrs Wilberforce trying to stop him chastising the said horse and Mrs Wilberforces umbrella with which she attempts to chastise Frankie Howard. Jack Warner (Dixon of Dock Green) plays the man in charge of the police station.
Its one of the best ever British comedies which also features quite a few 1950s railway scenes of steam engines, including inside what appears to be Kings Cross station, which is a bonus for railway enthusiasts like me. In one scene you also see that theres a railway track within a couple of feet of what is presumably the back of Mrs Wilberforces house. Only a wooden fence separates it from the house wall.
At the end of the street where her house is, you can see what seems to be (though it is somewhat blurred) an LNER sign (London and North Eastern Railway prior to the formation of British Railways in 1948), again suggesting Kings Cross station (which the locomotives, carriages, lines and tunnels in other scenes confirm it is meant to be, Copenhagen tunnel being specifically featured. If it was indeed LNER on the sign and looking down a real street one wonders why, as the film was shot in 1955, well into British Railways days.
A must for all comedy and railway buffs.
