Aside from Jaws, I don't feel there has been a really good shark movie. Sure, Deep Blue Sea was kind'a fun, but I can't find an excuse for something like Sharktopus. This video, posted by HuffingtonPost on August 14, 2012, provides a pretty fun collection of shark attacks in the movies--but be warned: it's probably not for the kiddies.
My favorite is the shark eating the airliner. That's quite an impressive feat...
I also love the music--somewhat reminiscent of Howard Shore's Lord of the Rings score.
If you have any crazy animal videos, let us know!
