It might say "based on a true story" on the poster but Whisky Galore! is really based on the classic 1949 Ealing comedy.
That was about a bunch of Scottish islanders, suffering the deprivations of World War II and starved of their favourite tipple, salvaging a shipload of whisky from a fortuitous shipwreck then hiding it from the authorities.
Yes, there was a true story behind it all. The original black-and-white movie came out while British wartime rationing was still in force. The reason for this technicolour, but strangely colourless, new spin isn't quite so clear.
Of course, whisky and whisky tourism is a big thing for Scotland. But there are better whisky appreciation movies than this rather twee period piece, especially Ken Loach's fine Angel's Share from 2011.
This repeats the usual things about whisky being "the water of life". But it's hardly much of an advert for it or its role in Scottish culture.
