While I suppose this is always dangerous, just having finished reading "The Men Who Made the Monsters" by Paul M. Jensen, I notice certain similiarities between the five men mentioned in the book--British director James Whale, American SFX artist Willis O'Brien, American SFX artist Ray Harryhausen, British director Terence Fisher, and British director Freddie Francis--and Ken.
But most of the similarities seem to be between Terence and Freddie and Ken, maybe because they came of age at about the same time and place; therefore, next time: "Ken and Terence."
