Just so that you can have a taster of Derek Thomas' favourite movie here is a clip of Huw's first day at school. This early attempt at Welsh accents was not the most succesful, with the exception of Dai Bando the boxer. It seems that tacking on an "is it" at the end of a sentence was the best they could do to make the dialogue authentically South Walian. Not to worry. Richard Burton, Anthony Hopkins and Catherine Zeta Jones have recovered the situation.
Please note just how appropriately English the school teacher is.
