Game of Thrones creators David Benioff and D.B. Weiss have now apologized for this:
It emerged on Wednesday that in a DVD commentary for season 1, the show creators said that one of the many decapitated heads that appeared on “Game of Thrones” last season was a prop likeness of Bush.
“The last head on the left is George Bush,” says Benioff, in the DVD commentary.
“George Bush’s head appears in a couple beheading scenes,” adds Weiss.
I mind, though I’d be surprised to hear George R.R. Martin minds.
And by all means hurry if you want an uncut copy of the DVD because HBO, offering profuse apologies of its own, has promised to remove the offending bit from future DVD productions.
