Admittedly "An American Werewolf in America" wouldn't have the same ring to it but having it located in London was a masterstroke as it enabled a good supporting cast of British actors to be used. The screenplay weakens but it does have some highpoints
Terrific set designs and wardrobe but the screenplay would have benefited from being more compact. If not more compact then shorter would have done. Kenneth McMillan is the standout for me.
