The best (worst) shark movies of all time

Posted: Updated:

Some films are so good they become socially important, but some films are so terrible that they unite America. Essentially, they're so bad, they're great.

Syfy's new TV movie, "Sharknado," generated a Twitter storm this week, which begs the question: Where can we find more of these shark-filled adventures? So, here are seven other shark films gone horribly, tragically right:

"2-headed Shark Attack" (2012)

If you think a one-headed shark attack or a tornado of sharks is scary, you haven't seen anything yet. Starring "critically-acclaimed" film vets Carmen Electra and Brooke Hogan, "2-Headed Shark Attack" tells the story of a beach community terrorized by a shark with two heads and will change the way you see animal mutations and terrible shark movies forever. 

Tag Line: "1 Body, 2 Heads, and 6,000 teeth!"

"Sand Sharks" (2011)

When an underwater earthquake opens a crater deep beneath the ocean's surface, a shark that can swim through sand is released. "Sand Sharks" also stars Brooke Hogan, the "Meryl Streep" of shark films.

 Tag Line: "Just When You Thought You Were Safe Out of The Water" 

"Dinoshark" (2011)

From Syfy studios, which also created "Sharknado," comes "Dinoshark," a TV movie about a prehistoric dinosaur-shark. The film features especially cheesy special effects and some unforgettable lines, like "welcome to the endangered species list, you bastard."

Tag Line: "Fear What's Just Below The Surface"

"Mega Shark vs Crocasaurous" (2010)

In the sequel to Syfy's "Mega Shark vs. Giant Octopus," a naval carrier is caught in the center of a battle between a megalodon and a 150-foot prehistoric crocodile. What may be even more ridiculous is that "Mega Shark vs Crocasaurous" stars Jaleel White, who played Steve Urkel on "Family Matters."

Tag Line: "Whoever Wins, we lose!"

"Mega Shark vs Giant Octopus"(2009)

Apparently the long-standing tradition of shark movies is to have incredible and unexpected actors in the starring roles. "Mega Shark vs Giant Octopus" is no different; it stars '80s pop star Debbie Gibson. The film is created by "Asylum," a studio known for artfully duplicating other famous franchises, including "The Terminators," "The Day The Earth Stopped" and "Street Racer."

Tag Line: "Winner... Eats...All!"

"Sharktopus" (2010)

The first film ever made about a half shark-half octopus and hopefully not the last because Syfy's "Sharktopus" is B-movie heaven. The film sports unforgettable death scenes, solid lead acting from Eric Roberts and its own theme song. Also, it's titled "Sharktopus." What more could you ask for?

Tag Line: "Half-Shark, Half-Octopus, All Killer"

Shark Attack 3: Megalodon (2002)

The greatest worst shark film of all: "Shark Attack 3." In what should be widely considered "The Room" of shark movies, a 75-foot prehistoric shark resurfaces and begins its reign of terror. No shark film better incorporates terrible graphics, painful acting and so much unintentional hilarity. Or maybe the writers are just more clever than we thought. Regardless, the result is a B-movie masterpiece that would be perfect for a drinking game, family movie night, (don't combine the two) or just one to keep in the collection.

Tag Line:"Say hello to the great-grandmother of say goodbye"

So that concludes our list of the greatest terrible shark films to date.
