I recently bought a box set of Ealing Comedies (Kind Hearts And Coronets, Passport To Pimlico, The Lavender Hill Mob, The Man In The White Suit and The Ladykillers) and looking back on them you do realise just how good British film comedy was around the 1940s and 50s.
One interesting thing which I have only spotted today is that the opening scene of The Lavender Hill Mob features one of the earliest screen appearances of Audrey Hepburn. I've never noticed it before.
