Will Hay delivers quite well in this wartime pick-me-up of a film. He is discovered to be the spitting image for a Nazi general who happens to be in charge of a prestigious Hitler Youth establishment. As you'd expect, his character "Potts" is the least like a general you can imagine, but soon he has been dispatched as a sort of doppelgänger and is causing the predictable havoc amongst the aspirational young men of the great Arian race. Hay always had solid entertainment skills, good comedy timing and a very expressive face - he easily raises a few chuckles here. Charles Hawtrey is also quite good fun as "Max" and there's even some Peter Ustinov faffing about as "Krauss" in this amiable farce that had a pretty clear propagandist purpose which I suspect would have worked well with audiences in Britain at the time. It's maybe a little long, but it does what it set out to do and as an example of the star's ability to chivvy up the viewers, it's a fair effort.
