The 1st thing I noticed when I opened the FOUR COLOR adaptation of 20,000 LEAGUES was, the art screamed "generic Gold Key art!" --even though this was a Dell, and GK didn't exist yet. But you know what I mean. Truthfully, if I didn't KNOW it was Frank Thorne, I'd never have guessed. It was also very obvious that Disney had not sent him ANY photo-reference AT ALL-- with the notable exception of The Nautilus. EVERYTHING else in the comic looks nothing like the movie-- the characters, the costumes, the visual storytelling. it's all "Frank Thorne". More or less.
But then, as I described in my long blog feature (and not nearly in as much detail as many other websites have), it seems from the word go, every single piece of merchandise spun off from Disney's 20,000 LEAGUES was apparently aimed at an entirely different market than the film was. The film was an often-INTENSE adventure story aimed at general audience (that includes ADULTS!!). The merchandise was aimed at KIDS. So all that really powerful, emotional stuff involving Nemo and his background and motivations, is NOWHERE to be seen. Mind you, most of it isn't in the published novel, EITHER... but that's besides the point!
