Stranger Things became such a surprise success that its crew needed tips from another extremely popular show on how to go about things moving forward. According to an interview by Entertainment Weekly with Stranger Things creators, they had to approach the producers of Game of Thrones on what to do when it comes to security protocols. “We literally consulted with the producers on Game of Thrones to learn security protocols,” say executive producer Shawn Levy. “I just knew I used to throw my sides away and now they have to be burnt,” says co-creator Ross Duffer of his daily shooting notes. The cast and the show itself now even gets code names. According to Millie Bobby Brown a.k.a. Eleven, “It’s this weird thing. On the call sheets our names are across it and if we lose it, we’re dead.”
Now, they’re hyperaware of the measures they need to take to make sure no spoilers get out. “We had no security protocols last season and we have extensive security protocols this season, Levy says. “I can’t speak about what they are because then people could crack them. We protect every story point, every page of every script.”
