The second in a series of Oakmont Films war movies with miniature ships is Submarine X1. Again this story is loosely based on a real mission, Operation Source, where a number of attacks were carried out on German battleships in Norway using midget submarines. The submarines were known as X class or X-craft.
This operation had also been previously depicted on film with Above Us the Waves from 1955.
Like
Attack on the Iron Coast, the miniature effects were once again mostly very effectively handled by the Bowie Organisation.
The shot of the depth charges rolling off the back of the German patrol boat suffers from being too small a scale miniature for such a close shot.
I have a feeling that the fictional Lindendorf battleship ship that is destroyed at the end may just be a large painted cutout rather than a miniature as the perspective never seems to change even when it is supposedly sinking and it is only ever seen at a distance.
