London
There are many accents traditionally associated with London. The most well known of the London accents long ago acquired the Cockney label from London's East End, which is heard both in London itself, and across the wider South East England region more generally. The accent of a 21st-century Londoner varies widely; what is becoming more and more common amongst the under-30s however is some fusion of Cockney with a whole array of ethnic accents, in particular Caribbean, which form an accent labelled Multicultural London English (MLE). The other widely heard and spoken accent is RP (Received Pronunciation) in various forms, which can often be heard in the media and many of other traditional professions and beyond, although this accent is not limited to London and South East England, and can also be heard selectively throughout the whole UK amongst certain social groupings. Since the turn of the century the Cockney dialect is less common in the East End and has 'migrated' east to Havering and the county of Essex.
English-language accents in film
Because of the Welsh language's musical quality, the Welsh English accent is difficult for non-Welsh actors to master. The language has Celtic roots like Irish Gaelic but is more arcane. Dialect coach Penny Dyer said, "The Welsh language has the loosest intonation system in the whole of the British Isles." The accent is more difficult than Irish and Scottish. For "How Green Was My Valley" (1941), set in Wales but filmed in California, director John Ford avoided depicting the Welsh accent by casting British and Irish actors who spoke with Irish accents. For the British film "The Englishman Who Went Up a Hill But Came Down a Mountain" (1995), director Christopher Monger sought to capture the accent onscreen by having actors Colm Meaney, Tara FitzGerald, and Ian Hart trained to sound like denizens of South Wales.
