Talk:Giant Tarantula/@comment-108.4.141.14-20130526045635

Possible reasons why the live tarantula wasn't used in the film over the CGI duplicate:

1) The performance wasn't preferable.  The tarantula being a real tarantula probably was pretty chilled out while for effect it needed to be frothing with anger and raring to escape it's cage.

2) The physics didn't look right.  Even though we may not all be versed in the finer points of science, we all have enough real world experience to tell that when something moves with the grace of a 3 oz arachnid that should be moving with the weight of a full grown horse something isn't right.

3) Wardrobe.  Something I've noticed about huge spiders in movies is this; when it comes to making a scary spider, the chubby ones shouldn't be hairy and the hairy ones shouldn't be chubby.  Hairy one's tend to have a sleaker hunting spider look.  The tarantulas have the slicked hair look to show you their girth.  There are some people who keep tarantulas as pets, and it seems like their cuteness appeal (if any) is mostly do to their chunky, baby fuzz look.
