'GoT' Author George R.R. Martin To Cameo on Syfy 'Z Nation'
It’s grown old hat to accuse Game of Thrones creator George R.R. Martin of stalling on the franchise’s sixth installment The Winds of Winter, most recently by the revered author’s Sharknado cameo, so we have good news and bad. Martin will put in a zombified appearance on Syfy’s Z Nation, but may also finally drop Winter in 2016, according to reports.
