This is one of those movies that evokes all the childhood memories. I still remember viewing this and as a kid and watching it recently it held its greatness. Sure it is a little silly. OK, a lot. That matters not though, big animals and the hysterics they cause may have been the stuff of 1950 B-Movies but it makes for a right old adventure as Digby becomes massive and wreaks havoc across the country. The special effects are obviously terrible but that all adds to the nostalgia, as does Spike Milligan. Above all else this is a slice of british history. Even from the subtleties of them eating breakfast in a british cafe, or the old cars. This is a hark back to a time when british were proud and the movies were innocent.
