North American English
There are a considerable number of different accents within the regions of both the United States and Canada, originally deriving from the accents prevalent in different English, Scottish and Irish regions of the British Isles and corresponding to settlement patterns of these peoples in the colonies. These were developed and built upon as new waves of immigration, and migration across the North American continent, brought new accents and dialects to new areas, and as these ways of speaking merged and assimilated with the population. It is claimed that despite the centuries of linguistic changes there is still a resemblance between the English East Anglia accents which would have been used by early English settlers in New England (including the Pilgrims), and modern Northeastern United States accents. Similarly, the accents of Newfoundland have some similarities to the accents of Scotland and Ireland.
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.
