A recently-announced porn spoof of George R.R. Martin's "Game of Thrones" may have seemed blasphemous to fans, but the author took a surprising stance on "Game of Bones: Winter is Cumming": He says it's not dirty enough.

When asked about the adaptation at the Santa Fe Film Festival, Martin said, "In the porn version that they're doing they've omitted the incest because that would just be too shocking. So my books are actually dirtier than the porn version!"

He's referring, of course, to the sexual relationship between Cersei and Jaime Lannister, who are twin siblings. Lee Roy Myers, the director of the film and a co-founder of WoodRocket.com, has said that his production company tries to "avoid incest as a running theme in porn."

The first five episodes of "Game of Bones: Winter is Cumming" are now available online; They star James Deen (of "The Canyons" fame) and April O'Neil.
