Don’t think I’ve ever seen this before: Syfy’s social media sensation Sharknado just delivered its biggest audience yet. Not for its premiere airing. Not for its second airing. But for its third airing — weeks after the film’s original telecast.

The campy horror film delivered a record 2.1 million total viewers, and 791K adults 18-49, on Saturday night. That’s the most-watched encore for an original movie in Syfy history.

What’s particularly impressive about the performance is that the film’s debut telecast — despite generating massive buzz on Twitter, clocking a whirlwind 5,000 tweets per minute during its peak — initially delivered a somewhat disappointing 1.4 million viewers a few weeks ago. But the social buzz continued after the film’s premiere. Then the second airing climbed to 1.9 million viewers. And now it’s crossed the 2 million mark.

There is, of course, a sequel in the works for next year, while the original Sharknado is getting the unusual honor of a limited theatrical release.

Sharknado will have its final Syfy airing this summer on Thursday, August 22, leading into the premiere of Ghost Shark. See the Ghost Shark trailer here.
