I spent the first few moments scrutinising the actors and comparing them to the original cast. But to the absolute credit of the cast I soon stopped doing that and simply enjoyed the episode. Unlike the poor recent film: the casting was spot on. Kevin McNally struck me as an odd choice for Captain Mainwaring but he nailed it. He obviously did his homework as Arthur Lowe's traits and mannerisms were all there. Robert Bathurst was also great as Sergeant Wilson and so much more believable than Bill Nighy in the film. I particularly liked Kevin Eldon as Jones who showed just how good a character actor he is. The story itself was fast paced and fun. It's such a shame that the original is lost as this is a strong episode. However everyone involved in this can be proud as it's is a piece of work to be proud of. If classics can be re-created this good maybe "Lost Dr Who episodes" could be made.
