People thought that Lynch's Dune was going to be the start of the next big franchise, they were making coloring books and other merchandise for it, including a cancelled attempt at a toy line by LJN, including action figures and vehicles, some of which never made it past the prototype stage, due to the film flopping.

Action Feyd with Milking Cat!
This site has some more imagery, including of those that never made it to market.
Alas, the world did not get a Gurney figure with Battle Pug.
This blog entry goes into some more detail about the toys, including the toy guys.
Holy shit! This can't be real! This is like that fake action figure set based on the movie "Caligula":
Of course, there was rumors that Star Wars was inspired by the Dune novel. I just can't see Dune working as a kid's popcorn movie without the addition of cute animal sidekicks and the subtraction of just about everything having to do with Baron Harkonnen (aside from his fatness.) Gods, can you imagine a He-Man-like Filmation series of Dune where Paul Atreides zooms around the deserts of Arrakis with a cartoon dog helping various villages defend themselves from the schemes of the evil Baron? Real life Saturday morning Cartoons have been based on premises that were just as weird.
That is an awesome poster. I'd love to get my hands on a full quality, full sized one.
