George R.R. Martin comes up with some brutal stuff.

The novelist whose A Song of Ice and Fire book series gave birth to "Game of Thrones" is executive producing another TV show, and it might be just as bloody. Syfy recently released a "Nightflyers" sneak peek that shows the violent opening scene. Not only is it gory, it's full of suspense.

Martin did previously warn that the TV adaptation of his "Nightflyers" novella and short story collection would be a "haunted house story on a starship." It centers on a mission into space that goes horribly, horribly wrong. The sneak peek shows the onboard chaos, yet leaves many, many questions unanswered.

Watch below, if you dare. As mentioned above, it's bloody.

The cast includes Gretchen Mol, Angus Simpson, David Ajala, Jodie Turner-Smith, Eoin Macken, Sam Strike, Maya Eshet, Phillip Rhys, Brian F. O'Byrne, and Gwynne McElveen.

"Nightflyers" premieres Dec. 2 at 10 p.m. ET/PT on Syfy.
