Foxtel's Universal Channel has confirmed it will screen early next month the "mockbuster" horror film about a storm of white pointer sharks literally raining havoc on America.

Despite Sharknado being shot for an estimated budget of about $1 million the absurd made-for-TV movie - with laughable special effects and actors who seem a second away from either cracking up laughing or just walking off in confusion - has become one of the most talked-about films of the year since it screened on America's SyFy Channel on July 11.

"This has been one of the most talked about films in a long time and we are excited to be able to bring it to Australian audiences," a Universal spokesperson said.

"We'll be airing it as part of our ongoing 'mockbuster programming block' on September 9 at 8.30pm. Monday night might not be a traditional party night but Sharknado will get the party started."

Starring former 90210 actor Ian Ziering and troubled teen star Tara Reid, the plot is this: a freak hurricane that has sucked up a shoal of man-eating sharks floods the streets of Los Angeles.

As the locals struggle through the rising waters, angry sharks rain down (and up again, for unexplained reasons) attacking anything in their way.

The heroes (Ziering and co) fight back by commandeering helicopters to meet the flying sharks on their own level.

It's beyond surreal - in one memorable scene Ziering arms himself with a chainsaw and leaps down the throat of an oncoming shark in a Rambo-meets-Jonah moment - but became an instant hit, trending worldwide on Twitter largely because a string of high-profile film industry executives found the film on TV and fell in love with its absurdity.

"Holy shit," wrote Lost creator, Star Trek producer and Prometheus writer Damon Lindelof. "Steve from 90210 just said, 'If there's one thing I hate more than chlamydia, it's god dammed sharks."

"Clearly SyFy is employing the old, 'so bad, it's good' method with tremendous effect. #TrendingForHours," added The Shield star Michael Chiklis.

In all, more than 604,000 tweets emerged about the show, more than the controversial Game Of Thrones' Red Wedding episode. Before the film had even finished, Lindelof was back with: "I am going to write the Sharknado sequel and I am going to do it before Shaknado is over."

From production/distribution company  The Asylum , Sharknado is the latest in a string of "mockbuster" films the company churns out, usually to cash in on the publicity of existing box office hits.

They have, for example, brought out films called Transmorphers, Snakes On A Train, Abraham Lincoln Vs Zombies, The Amityville Haunting, Sunday School Musical and dozens more "homages" to existing films.

This wasn't even their first shark-based effort, with Mega-Shark Vs Crocasaurus released two years ago.

Despite the social media buzz, however, the movie did not rate particularly well in the US, with just 1.4 million viewers, less than one-eighth of the week's ratings winner Under The Dome (which attracted an audience of 10.4 million).

That may be enough, however, for Asylum to greenlight a sequel.

Tara Reid has already said she would act in any follow-up, and despite Lindelof's enthusiasm to write it, Sharknado's original writer Thunder Levin said he was "definitely" looking at a second chapter, possibly exploring the use of other animals who turn violent after a natural disaster.

Twitter users have been suggesting ideas to Levin. His favourite so far: "SnailQuake," he said straightfaced. "But it could be slow moving."
