"Richard Parker turned and started clawing the shark's head with his free front paw and biting it with his jaws, while his rear legs began tearing at its stomach and back. Richard Parker's snarling was simply terrifying."
Yeah, so I never actually read "Life of Pi" beforehand. (There are only so many books one human being can read in a lifetime. So sue me.

) And the obvious CG in the movie for Richard Parker was... well, obvious. But then, it would be all but impossible to get a tiger to do everything they needed it to do in the movie, so I can't fault them.
By the way, this is not the real Richard Parker. Obviously. xD
This is the awesome Anala, the bengal tigress from the Franklin Park Zoo, Boston.
Thanks!
The title her is a reference to "Life of Pi."
but really sugoiXD
