The Green Man (1955 Robert Day)

A jaunty thriller in which a woman (Avril Angers) is murdered and left in a piano - something Alastair Sim's character finds most distasteful - she's not been murdered, either, thanks to John Chandos's ineptitude. Sim is an assassin who favours the fat and pompous. Meanwhile George Cole's discovery of the body (and of Jill Adams' body) gets him into hot water with her fiancé Colin Gordon (who looks like my dad). They then at the Green Man of the title interrupt an extremely seedy evening with politician Raymond Huntley and a wet weekend of a girl who he's taken on a romantic break - Eileen Moore, who was Mrs Cole until 1962.  And they also encounter Terry-Thomas, publican Arthur Brough and Dora Bryan (A Taste of Honey), and a trio of musicians.

Written by Launder and Gilliat, from their play 'Meet a Body'. Scored by Cedric Thorpe Davie and shot by Gerald Gibbs.

Wasn't Alastair Sim a distinctive talent? There's no one else quite like him. Film also gives Jill Adams one of her best parts.
