In reply to gd303uk:
Good calls (remind me what Let it Ride is though, not sure that I know it)
I used to be addicted to watching Let it Ride.
I think there are an awful lot of dull moments within the Ealing classics, and some forgotten ones which can put the lie to "any Ealing comedy is great", but your examples are grand (though The Man in the White Suit is as much downbeat conspiracy as it is comedy)
I think The Lemming would do well to watch Condorman and Mystery Science Theatre 3000: THe Movie
