Scloyd...watched the original "Whisky Galore" a few years back.
It is, indeed, a gem of a movie.
If you liked that then you'll probably enjoy other Ealing comedies (named after the British studio that made them).
There are loads and loads but the best ones (in my opinion) are:
The Ladykillers (not the Tom Hanks remake though)
The Lavender Hill Mob
Kind Hearts and Coronets
Passport to Pimlico
The Man in the White Suit
They're all in a similar style to Whisky Galore! ie genteel British comedies from the 1950's and as well as the ones I mentioned there are many more.
Alec Guinness is in quite a few of them as well as others you'd recognise like a Pre-Holywood Peter Cellers.
Anyway they're classics of British cinema and are well worth a shufti.
