We provided over 650 Fish for Godzilla. At the beginning of production, a test was conducted using real fish and the resulting smells that quickly developed led to a decision to go with artificial fish. WThe bodies were solid silicone rubber, greatly softened with thinners for added realistic flexibility. All of the fins had to be made separately and joined on so they would be much stiffer than the softened rubber, which would have flopped over at those thicknesses. Realistic fish scale patterns were painted on by starting with a base green rubber color and painting through a fine screen with silver, then glazing over this layer with white for the bellies and pearlescent colors on the sides to achieve the iridescence of trout. High quality glass taxidermy eyes were used for their bright, hard highlights and k-y jelly was used to keep any water present from beading up unaturally on the fish.

To achieve the outrageously huge piles of fish that appear in the movie, big piles of our fish were simultaneously gang-molded in flats from which large latex sheets of fish were cast & painted, and thrown over big air bags on set. For the scenes of fish still kicking along Godzilla's trail, we built an additional six fully self enclosed, animatronic, kicking fish.
