We've been hearing for months now about 'Pacific Rim' director Guillermo del Toro's FX vampire drama, 'The Strain,' which already has accrued an incredible cast despite lacking an official series order. Speaking from the TCA press tour, FX president John Landgraf offered an update on the series, all but assuring a multiple-season order, while previewing horror and gore on part with 'The Walking Dead.'

“When Guillermo [and his team] came in to sell it, one of the things they made clear is that they wanted to tell the story of the books, and that story would be told over three, four or five seasons,” said Landgraf, despite the fact that FX has commit to nothing beyond the pilot episode. Adding that the series would unfold between 39 and 65 total episodes, the network head capped things off with "no more, no less."

Based on Del Toro’s 2009 novel trilogy, ‘The Strain’ follows Dr. Ephraim “Eph” Goodweather (‘House of CardsCorey 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 Roger Cross ('24'), Robert Maillet (‘Pacific Rim‘), Mia Maestro (‘Alias’), John Hurt (‘Hellboy,' ‘Doctor Who‘), Lauren Lee Smith, Miguel Gomez, Kevin Durand (‘LOST‘) and Richard Sammel (‘Inglorious Basterds’). Former ‘LOST’ and current ‘Bates Motel‘ showrunner Carlton Cuse will helm FX’s adaptation from a screenplay by Del Toro and novel co-writer Michael Hogan. Hogan and Gary Ungar will also serve as executive producers.

Landgraf assured reporters that 'The Strain' would feature horror on par with AMC's 'The Walking Dead' or FX's own 'American Horror Story,' but what say you? Are you convinced we'll be seeing 'The Strain' on TV before long?
