Kind Hearts and Coronets (1949)
This, for instance, from the executioner who plans to retire after hanging the Duke of Chalfont (our anti-hero) because,"After using a silken rope, I'll never again be content with hemp."
It's the story of a young man who tries to regain his birthright from the family who wronged his mother (an heir to the dukedom of Chalfont) for having married beneath her. Louis D'Ascoyne Mazzini (Dennis Price; on whose later work, including this, I shall not comment) can only inherit the dukedom if eight family members (all Alec Guinness) before him kick the bucket. Suffice it to say that by the end of the picture he is the 10th Duke of Chalfont.
As per usual with Ealing Studio films of this era, the audio leaves much to be desired, particularly if you're American with need of a little amplification to decipher the British mumbling. Happily, Ealing has remastered Kind Hearts among a number of its classics, so this will no longer be an issue for us colonials.
Please do see it if you can. It's one of my favorites; a smart, funny, beautifully told dark comedy.
