Reactions have been somewhat mixed toward FX's Guillermo del Toro vampire thriller, 'The Strain,' but if you thought the network would look to contain a spread like that, you're sadly mistaken. 'The Strain' will officially continue to infect TV sets through 2015, having been renewed for a second season of post-apocalyptic horror.

Averaging approximately 11 million viewers in its Sunday timeslot, 'The Strain' had very little likelihood of being canceled, considering the network's partnership with Guillermo del Toro and the increasing visibility of series lead Corey Stoll, hairpiece and all. In any case, del Toro has frequently gone on record to cite a five-season projection for the series, parsing the material between him and co-creator Chuck Hogan's novel trilogy.

Says FX President John Landgraf of the renewal:

We've never had any doubts about 'The Strain.' Working with Guillermo del Toro, Carlton Cuse, and the brilliant cast led by Corey Stoll has been everything we had hoped it would be and more. It is thrilling when you have a show that is a creative and commercial hit, which is a rare accomplishment in this increasingly crowded marketplace. We look forward having it on FX for as long as Carlton, Guillermo and Chuck Hogan need to tell this epic tale.

Chimes in del Toro:

I am thrilled! Another season to spread the virus!. Working with Carlton, Chuck and FX has been immensely rewarding and we have such sights to unveil in the upcoming episodes—the blood hits the fan on this one, mankind becomes an endangered species.

Based on del Toro’s 2009 novel trilogy, ‘The Strain’ follows Dr. Ephraim Goodweather (‘Ant-Man‘'s Stoll), a CDC operative who investigates a mysterious viral outbreak with hallmarks of an ancient and evil strain of vampirism. As the strain spreads, Eph, his team and an assembly of everyday New Yorkers wage war for the fate of humanity itself.

Also present among the cast are Regina King, Sean Astin (‘Lord of the Rings‘), Roger Cross (‘24‘), Leslie Hope, Robert Maillet (‘Pacific Rim‘), Mia Maestro (‘Alias’), Lauren Lee Smith, Miguel Gomez, Kevin Durand (‘LOST‘), David Bradley (‘Game of Thrones,’ replacing John Hurt) and Richard Sammel (‘Inglorious Basterds’). Former ‘LOST’ and current ‘Bates Motel‘ showrunner Carlton Cuse helms FX’s adaptation from a screenplay by del Toro and novel co-writer Chuck Hogan.
