A sequel to the disaster movie which made a viral splash earlier this year has been announced, with producers taking to Twitter to request fan suggestions for taglines.

"Enough said" was the tagline for the original Sharknado, the cable disaster flick about a freak tornado which triggers scores of man-eating fish to rain down on the residents of Los Angeles.

But following a surprise storm of happy chat generated by the cable premiere of the film a fortnight ago, Asylum Films, the production company behind the film has decided to keep the conversation going a little longer, announcing that a New York-set followup with be released in 2014.

When the film premiered on the Syfy network in on 10 July, it reeled in just 1.3 million viewers; fewer than average for an original film on the network. But those who did watch turned out to have unusually twitchy fingers; over 5,000 Sharknado-related tweets were minute were recorded during the film's more exciting moments (for instance when a surfer called Fin chainsaws his way out of a shark's mouth – with Tara Reid).

Syfy's Thomas Vitale credited the small screen berth with the commissioning of a followup. "Every once in a while, there is a perfect storm – on television. The fans are clamouring for a sequel. Or perhaps it will be a prequel. What we can guarantee is that Sharknado 2 will be lots of fun. We'll be announcing more details very soon. But we didn't want our fans to worry they wouldn't get their fill of more shark fin, I mean, fun next year."

And in further acknowledgement of the importance of the film's social network champions, Syfy has invited people to tweet suggestions for the sequel's tagline using the hashtag #Sharknado. Submissions so far include "Sharknado 2: Electric Boogaloo", "Sharknado 2: Sharks and the City" and "Sharknado 2: Taking a Bite out of the Big Apple".

Sharknado premiered at the market in Cannes in May this year, where it was awarded the honour of being named one of the Guardian's worst posters of the festival.
