Two influential fantasy characters — John Carter of Mars and Conan of Cimmeria — are coming to the silver screen, but a quick comparison shows just how differently the two directors are approaching their adaptations:
Just take a gander at the IMDB listing of the cast of characters for a moment. What you see there is a listing consisting nearly completely of characters who actually appear in Barsoom tales written by Edgar Rice Burroughs. Indeed, unless I am mistaken not a single named character of significance in the film is an invention of Stanton or his co-writers.
Compare this to the similar listing of the cast of characters in the upcoming Conan the Barbarian, where, aside from the titular Cimmerian, none of the characters has any basis in the source material.
