Have you seen all of the Gamera series?
In the first one, he was made by a nuke blast in the arctic.
In the remake, he was engineered by an ancient civilization to defend against Gyaos.
The latest movie was released in Japan (Called, "Gamera: The Little Braves") this year.
If you haven't yet, go watch the third of the new series, "Revenge of Iris." It is the best in storyline, FX, camerawork and all sorts of other things not seen in these kind of movies before. Excellent movie.
Thanks--i'll check it out.
gamera is big in our family.
i even have a "movie poster" painted by one of my daughters of gamera fighting king kong!
