It takes a bit of tweaking to get a character right for a movie, especially if it's science fiction or a comic book adaptation. What looks good on paper often doesn't translate all that well to the screen. So it's common that early drafts are tested out and changed considerably before production. Sometimes those early ideas were just plain stupid.
But thanks to archived art and screen tests, we can see what those early and awful ideas were like. Aren't you glad they tried again and again until they got it right …or at least better? -via the A.V. Club
