It’s happening and there is nothing we can do to stop it.
I, for the life of me, am not really sure why Sharknado was the internet sensation that it was. Scratch that, I know exactly why: it’s because of the title. And that’s all. I know this because there was another movie of similar quality about sharks that live in the snow on a mountain except instead of calling it “Sharkalanche” they called it “Avalanche Sharks” and you just can’t sell that because it’s not a portmanteau.
Anyway, here’s the poster for Sharknado 2: The Second One thanks to io9. Highlights of the film apparently include New York City, at least five separate sharks, and presumably Ian Ziering chainsawing at least 2 of those five sharks.
