Sequel to The Mouse That Roared (1959), the tiny country of Grand Fenwick has a hot water problem in the castle. To get the money necessary to put in a new set of plumbing, they request foreign aid from the U.S. for Space Research. The Russians then send aid as well to show that they too are for the internationalization of space. While the grand Duke is dreaming of hot baths, their one scientist is slapping together a rocket. The U.S. and Soviets get wind of the impending launch and try and beat them to the moon. Written by John Vogel <jlvogel@comcast.net>

"But we've got pudding!"
27 January 2021 | by Brucey_DSee all my reviews

If you have not yet seen either 'Mouse' film, it is probably better to see this one first, rather than view it with expectations raised by the other one.

It is easy to forget that this film was made before there had been any moon landings; plot points such as dust on the moon were real concerns for the Apollo astronauts when they landed for real, some years later. The planting of a flag (although not the first seen on film of course) was either prescient or life imitated art later on...?

Oddly enough both the look of the moon and the look of the rocket's interior are strongly reminiscent of those seen in the Wallace and Gromit animation 'a grand day out', which must surely have been inspired by the 'Mouse' film.

This film does appear on UK TV from time to time; for example on the Sony Movie Classic channel. However this raises my main disappointment concerning this film; the Sony 'watermark' is huge and obtrusive as usual, but the conversion from Celluloid to PAL video which they broadcast is almost an object lesson in 'how not to do it'; goodness knows what they did (possibly started with a bad print, converted badly to NSTC and then badly to PAL?) but the result is fuzzy, jerky in places, with poor/unsynchronized sound quality. The net result is pretty execrable; in places I'd describe it as 'almost unwatchable' in fact. This isn't the best film ever but my enjoyment of it was seriously impaired by the rotten quality of the broadcast video. I can only suppose (and hope) that commercial DVDs are better than that; they surely can't be worse...?

Six out of ten from me; might have been more but for the rotten video quality.
