Do n'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 791,000 adults 18-49 on Saturday night . That 's the most-watched encore for an original movie in Syfy history . 'Sharknado ' producer : Tara Reid is n't fired from sequel . 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 . First official trailer for Syfy 's 'Ghost Shark ' 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 .
