Nearly five years after signing their big multi-million dollar Netflix deal, “Game Of Thrones” creators David Benioff & D.B. Weiss are finally set to begin at the streamer in earnest with their first big project, the sci-fi mystery series, “3 Body Problem” (to be fair, they executive produced Netflix’s “The Chair” too, but that was more of Amanda Peet and Annie Julia Wyman’s project; Peete is married to Benioff).
