The Two Mrs Cranes is one of my favourite episodes. The only bad thing about this however, is the actor who plays Clive, he obviously went to the Dick Van Dyke school of English accents! It drives me nuts and I'm Scottish. Also Daphne has a number of brothers, most of whom, especially Simon, have southern english accents however, Daphne is supposed to be from Manchester in Northern England, quite a different accent!
Surely it would have been possible to find actors who could act using the relevant accent. I guess most Americans would not really pick up on this however it is as blatant as having a New Yorker trying to pass himself off as Texan.
