Going on months now, we've heard plenty of casting reports from FX's Guillermo del Toro-adapted vampire thriller 'The Strain,' though little in the way of a highly-anticipated series order. That process continues today, as '24' vet Roger Cross has been announced to join the massive ensemble in an action-heavy role, but as whom, you ask?

According to Deadline, the occasional 'Arrow' star will take the recurring role of Mr. Fitzwilliams, head of security and caregiver to Palmer’s (Jonathan Hyde). Based on Del Toro’s 2009 novel trilogy, ‘The Strain’ follows Dr. Ephraim "Eph" Goodweather ('House of Cards' Corey 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 'Pacific Rim' behemoth Robert Maillet, ‘Alias’ star Mia Maestro, ‘Hellboy‘ and ‘Doctor Who‘ star John Hurt, 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.

As previously mentioned, FX has yet to issue a series order for the buzzworthy adaptation, despite the increasingly impressive pedigree of its cast and crew. Tell us in the comments if you want to see 'The Strain' make it to TV next year!
