Is caricature necessary for profit?

Quote from an article on the films of Satyajit Ray, a legendary (non-Bollywood) Indian filmmaker, and giant of world cinema of whom Akira Kurosawa (legendary Japanese filmmaker, whose work was widely ripped off by Hollywood filmmakers) said "not to have seen the cinema of Ray means existing in the world without seeing the sun or the moon" (quoted in Aditya Chakrabortty's article):

Perhaps for a culture to thrive in international trade it must serve up a caricature of itself.

Do we think this is true of British cinema? Is it inevitable that the twisted-for-US consumption depictions of the UK (almost always S.Eng) we see in many WT films will always do better business than Warp's less glammed-up representation (sumulacra?) of Britain?
