FX has given viewers their first official look at The Strain.

Following a number of brief, creepy, mysteriously awesome promos, the network has now come out with a 30-second trailer that features actual footage from the upcoming drama.

Starring Corey Stoll as Dr. Ephraim Goodweather, The Strain is a small screen adaptation of Guillermo del Toro and Chuck Hogan's series of vampire novels/comics.

It centers on a Center for Disease Control Canary Team in New York City that is called upon to investigate a number of viral outbreaks with hallmarks of an ancient and evil strain of vampirism.

Intrigued? Just wait until you watch this preview...

The Strain premieres on July 13.
