Music has always played an intrinsic part in British films; look at 'Scott of the Antarctic' and the way that Vaughan Williams depicted this environment in the music. 'Curse of the werewolf' from Hammer in the 1950s was among the first films to use atonal effects for weirdness, long before it happened again with 'Alien'. Even John Williams copied the English musical style at the end of Star Wars.
Even noticed that the 'baddies' in Hollywood films have always had English accents? From Colin Clive in 'Frankenstein' through Peter Lorre, George Sanders and Peter Cushing in Star Wars. Must be the accent and the ability to raise one eyebrow.
These days, the only really saleable British film that even gets recognised transatlantically is the ubiquitous upbeat-romantic-comedy type, and even then we (occasionally) have to rely on a Hollywood star wearing a British accent - very well indeed, in Renee Zellweger's case - to sell it over there. Which will be Ewan MacGregor's most recognised roles - Obi-Wan Kenobi (where he's mostly slept through the part so far in episodes 1 and 2) or the UK-based films he's starred in this year?
Having said that, I enjoy a good film, with chocolate covered raisins and a cup of coffee. (And my mobile phone turned off, of course.)
