It looks like upcoming FX series The Strain is taking a page from sister series American Horror Story and releasing conceptual teasers for the show. If you watch other shows on FX you’ve likely seen the one we posted back in January, which I’ve included below. The new one, however, is much more disturbing:

Synopsis:

The Strain is a high concept thriller that tells the story of “Dr. Ephraim Goodweather” (Corey Stoll), the head of the Center for Disease Control Canary Team in New York City. He and his team are 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, starring Corey Stoll, Mia Maestro, Sean Astin, David Bradley, Kevin Durand, Natalie Brown, Jonathan Hyde, Richard Sammel, Robert Maillet, Jack Kesy, Ben Hyland, and Miguel Gomez, premieres this summer on FX.
