Murphy's War 1971

A largely forgotten film that has some very creditable miniature effects shots.

There are underwater shots of a Nazi submarine, shots of the submarine facing off a dilapidated crane barge and  shots of the crane barge sinking at the end of the movie. The torpedo looks to be a commonly used stock shot.

I have no idea who supervised the miniature work. It looks very like Bill Warrington's work. I would like to know if any one could furnish me with this information, I would be very interested to find out, please add it to the comments.

Sailors Three 1940

Thanks to Dennis Nicholson for putting me onto this title.

The miniature special effects by Roy Kellino and Douglas Woolsey are pretty typical for British films made during the Second world War period. You get the sense that resources were much tighter than for their American counterparts. For one thing Britain was well into the war, materials would have been scarce while America still had another 2 years before entering the fray. The film would have been released around the time of the Battle of Britain.
