Produced by 20th Century Fox in Britain, this odd little film has apparently two different endings, I saw the one with the happy ending. I can find no information on the visual effects or the miniature effects personnel for this film, there isn’t even any credits for special effects.
A film I had never heard of until suggested by a reader Simon. It has some pretty extensive miniature sequences concerning Motor Torpedo Boats, E boats and submarine pens housing glider bombs on Sicily during World War 2. It was shot entirely on the Island of Malta, and I am guessing as was the miniature work. I can find no information about the miniature work which is not even credited in the film except for a special; effects man which does not necessarily encompass the model work it usually means the live action bullet hits and explosives etc.
For the most part there is much creditable work on show, there are some great shots of the boats roaring about. Some of the boat explosions could have done with more scoring on the models so they break up into smaller pieces, they tend to come apart along the line of superstructure and hull and there are a few background ships that look like simple painted cutouts.
Batman the Movie was released in the same year as the previous post entry Assault on a Queen, and as suggested by the http://www.moon-city-garbage.agency website, used the same submarine miniature, though with a new paint job and some significantly comical modifications. Similarly the full submarine set is also re-used here in the Sersen tank with the same painted backing as used for the miniatures.
Special Photographic effects supervised by L.B. Abbott.
Some pretty decent miniature work here supervised by Lawrence Butler, although it suffers occasionally from being able to see the tank wall. Also a common deficiency in most submarine films is too great a visibility due to unrealistically clear water. There is also a very weak periscope shot with a painted ship that looks like a cartoon. One other split screen shot showing the effect of a flash powder charge detonating on the side of the Queen Mary clearly shows the sailors heads passing through the matte line.
Thanks to a reader Pete for putting me on to this film and for the link to this page and website http://www.moon-city-garbage.agency which has some very interesting articles and pictures on old school visual effects.
