Let Guillermo del Toro be your personal guide through the world of FX's The Strain. A new featurette takes viewers behind the scenes of this unique thriller created by the iconic filmmaker of such cult hits as Pan's Labyrinth and Hellboy. A new strain of vampirism is infecting the citizens of New York, and only one man, Dr. Ephraim Goodweather, can find the source of the cure. Watch as stars Corey Stoll and Sean Astin discuss the authentic reality brought to the story, along with never-before seen footage, debuting this summer, only on FX.

Dr. Ephraim Goodweather, the head of the Center for Disease Control Canary Team in New York City, is called upon to investigate 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.

The Strain premieres Sunday, July 13 at 10p on FX.
