What are your must-see British holiday-themed comedies? I can't think of a better year to binge watch Christmas movies.

Holiday on the Buses. I would have liked to be on that holiday so I could give Olive one.

Carry on Camping - my absolute favourite of the series.

I'd agree totallly with the two suggestions above, Carry on Abroad is a poor cousin to Camping but worth a giggle, never watched Benidorm but mother in law rates it, apart from the seaside bit on Carry on at Your Convenience, I can't think of any more.

Since the OP specifically mentioned Christmas "movies" (sic, it's got to be "Scrooge" with Alastair Sim hasn't it? There's also "The Holly & the Ivy" with Ralph Richardson and Celia Johnson.

Otherwise all my must-watch Christmas films tend to be American - "It's a Wonderful Life", "Miracle on 34th Street", "White Christmas", "The Shop Around the Corner", etc.
