I saw the movie, Gorgo, when it was first released. There was also a comic book adaptation published by Charlton. In that way memory works — or doesn’t — I don’t remember anything about the movie, but I do remember being knocked out by Steve Ditko’s artwork in the comic book. I was (and still am) especially taken by those underwater scenes. Perhaps it is the comparison of Ditko’s art to the rest of the contents of Gorgo #1 that gives one the impression that the artwork for the back-up features seems indifferent, and serviceable at best. (Sorry, Charlton fans.)
There were a few more issues of Gorgo by Ditko out of the total series, which appeared through 1965. I only bought the issues he drew.
