Visual Tricks and the movies

So I popped in the "original" Star Wars trilogy DVDs last night and watched some of my own selected favorite scenes. Afterward, I was thinking about something I learned about human vision and visual tricks in my AI class.

When your brain sees a visual trick that seems like it should make sense, but is obviously a trick (see Walter Wick's Optical Tricks ) we are drawn to it, because our brain strives to understand the trick. However when we see something visually that obviously makes no sense, we just ignore it because we simply chalk it up as absurd, there is nothing to solve.

There is an analogy in the use of CG in movies. When you see Luke use the force to draw his light saber to his hand from the floor in "Empire Strikes Back", we look at the trick and wonder, "I bet they used a wire to move the saber through the air." And we say "That was a good trick." When we see Yoda doing ridiculous flips through the air in "Attack of the Clones" we easily realize that it is CG and we ignore how it was done. "It was just a computer."

BTW, if you haven't make sure you watch the old trailers and TV spots on the bonus DVD. They are priceless. I especially liked the voice talent and how the teasers often used story board illustrations instead of any real scenes from the film.

did you check out the commentary tracks? Most of it is pretty useless and rather boring, but some of it was interesting as well. Mainly the tracks from Lucas himself about the development of story lines. One of the more interesting was on ROTJ where he talks about how he had originally planned to have Wookiees battle the Stormtroppers instead of Ewoks. However, since Chewie became a central character in the other movies he decided to go with the Ewoks. Big mistake.
