The director Ken Loach has set several of his films in South or West Yorkshire and has stated that he does not want actors to deviate from their natural accent. The relevant films by Loach include "Kes" (Barnsley), "Days of Hope" (first episode in south of West Yorkshire), "The Price of Coal" (South Yorkshire and Wakefield), "The Gamekeeper" (Sheffield), "Looks and Smiles" (Sheffield) and "The Navigators" (South and West Yorkshire). Loach's films were used in a French dialectological analysis on changing speech patterns in South Yorkshire. Loach said in his contribution that the speech in his recently-released film "The Navigators" was less regionally-marked than in his early film "Kes" because of changing speech patterns in South Yorkshire, which the authors of the article interpreted as a move towards a more standard dialect of English.
