I definitely do not agree that this film is a bit of a let down (as another commenter suggested).
Although this is considered to be a "B-movie", it possibly contains Bernard Bresslaw's finest ever performance. He is absolutely brilliant as Snowdrop. Another class act is John Le Mesurier as the judge when Billy Gordon (Terry-Thomas) goes to court. On top of that you've got Sid James being one of his best known characters (i.e. the down at heel crook he played in Hancock's Half Hour on radio and TV and in the film Father Brown), George Cole as an early Arthur Daley, but a bit more on the wrong side of the law than Arfur ever was, and a supporting cast containing the likes of Nicholas Parsons (a great B-movie actor, unfortunately now better known as a game show host), Brenda de Banzie,Vera Day and Joe Melia. The plot was later used to provide the basis for the American film Ruthless People. As usual, a British B-movie shows incredible attention to detail (the "Keep Death Off The Road" gag and the van they finally arrive at St Albans with Gordon's kidnapped wife spring to mind). The scene where Gordon's wife returns is worth watching the rest of the film for, even if you aren't too keen on it (although I personally think this is one of the best films ever made, so I know I'm biased!).
