20 Things You Somehow Missed In Toy Story
12. All The Animation Short-Cuts
In addition to making Andy's friends copy-paste clones of himself, Pixar also employed a number of other sneaky animation short-cuts to lighten their load.
Most prominently, none of the movie's human characters have long, flowing hair, because Pixar was still wrestling with the complex mechanics of hair physics at the time.
This is the reason that Andy's mother has her hair tied up in a pony tail and Sid's sister Hannah has a short, solid bob: to save the animators having to figure out a volumetric model for it.
There are other time-savers: we don't see Combat Carl's explosive death because Pixar considered animating an explosion too taxing, and there are no milk droplets when Woody dunks his burning head into Sid's bowl of cereal for much the same reason.
