I always felt that Herbert Lom had a wonderful face for comedy; and here I think he stands out alongside Cecil Parker - always underrated, but who could be relied upon to deliver a standard of comedy haplessness consistently well on screen. Guinness and Sellers are doing what we know they are good at, so I was less impressed by them in this one. Katie Johnson gets many plaudits as "Mrs Wilberforce", though I wonder how much acting she was actually doing? Any interviews I have seen with her seem to suggest she was pretty much playing herself in this slightly more sinister of the Ealing comedies... læs resten.
