Perhaps the TV show was just too good, or having the Germans land in Walmington was just too improbable. Whatever, this film version of the much-loved BBC classic doesn't quite work. Everyone in it is fine but it is less slapstick and silly than it was on the small screen, and suffers a bit in comparison. I do like the bit where the stuck up officer sails down river on a bit of broken bridge still sitting on his horse though, and the oil slick machine is pretty funny!
