Gorgo (1961)

For many, Gorgo is considered the poor man’s Godzilla. When Gorgo first hit the movie theaters during the early 1960s I was there in the audience enjoying the film. What is unusual about the plot for Gorgo is the monster and her baby both escape unharmed at the end of the film. The building of this diorama was straightforward with no particular problems. The mold seams needed to be smoothed and all gaps were filled with Aves apoxie putty. All paints were acrylics.

From Wikipedia:

Gorgo is a 1961 British science fiction monster film directed by Eugène Lourié. The film focuses on Gorgo, an ancient sea creature brought back to London for exploitation but eventually stirs its mother’s attention, who rampages across London to search for her offspring. The film was featured in an episode of the cult movie-mocking television show Mystery Science Theater 3000.
