Mr. Sardonicus

I remember seeing Mr. Sardonicus, a 1961 horror film directed by William Castle, on late-night tv when I was a younger teen. The scene I remember best is the one with the dogs which had been used in the experiments.

WTF Film says, "one of the better films in Castle’s filmography, especially for people with an interest in Gothic horror beyond the initial Universal wave, Corman and Bava."
