Brides of Fu Manchu 1966

Thanks to Dennis Nicholson for spotting this title which features a couple of shots of a model ship that appears to have been photographed on location, probably just being pushed on a dolly. The ship looks like it may have been a display model from a shipping company although it does not match either of the two actual ships that were named "Windsor Castle".

It is followed by a dodgy split screen superimposed explosion where the matte line is clearly visible.

There is also a miniature aerial/ death ray and a sort of mountain/ volcano/ pile of rocks which is the baddies base which explodes at the end.

Note prominent horizontal split screen matte line just under both ships.

The Lost Continent 1968

Some atmospheric model ship shots in this famously off the wall film. Miniatures supervised by Cliff Richardson a renowned figure in British special effects.

I presume the credit for  Robert A. Mattey was for the assorted full size mechanically operated monsters that appear in the latter stages of the film. He was most known for the giant squid that  is seen in 20,000 Leagues Under the Sea  in 1954 and "Bruce" the shark in Jaws in 1975.

The one criticism I have is that the stagnant sea is just too flat for scale realism and would have been more effective if it had had some fine ripples on its surface.
