"Stranger Things" Season 2 is one of the most awaited television series to return to the small screens. As Netflix wants to remain things under wraps, the show's executive producer Shawn Levy called on the people behind the success of "Game of Thrones" to ask for some advice to keep every detail sacred.

"We literally consulted with the producers of 'Game of Thrones' to learn security protocols," Shawn Levy told Entertainment Weekly. The film director revealed that they had no set of rules in the previous chapter, thus they now decided to have an extensive safety procedure in the coming "Stranger Things" Season 2.

However, Shawn Levy revealed that he can't talk what kind of security measure they used as some people have the ability to crack it. Hence, he just said that they protect "every story point" of "Stranger Things" Season 2 as well as "every page of its script."

"I just knew I used to throw my sides away and now they have to be burnt," the show's co-creator Ross Duffer added. Millie Bobby Brown, who plays the role of Eleven, also revealed she and the rest of the cast put "Stranger Things" Season 2 in secrecy.

 Millie Bobby Brown described that they now all have surreal code names in "Stranger Things" Season 2. "It's this weird thing. On the call sheets our names are across it and if we lose it, we're dead," she said.

Meanwhile, as Netflix keeps the details of "Stranger Things" Season 2 under wraps, Digital Spy revealed the small things known about the show. The boys will definitely back. Mike (Finn Wolfhard), Dustin (Gaten Matarazzo), Lucas (Caleb McLaughlin) and Will (Noah Schnapp) will be once again seen in another adventure, of course, with Eleven.

Joyce (Winona Ryder), Karen (Cara Buono) and Jim (David Harbour) are also returning in "Stranger Things" Season 2. Also, the love triangle between Jonathan (Charlie Heaton), Nancy (Natalie Dyer) and Steve (Joe Kerry) will be once again witnessed. Netflix announced that new episodes of the show will be dropped on Oct. 31.
