Stranger Things creators, Matt and Ross Duffer recently sat down with The Hollywood Reporter to talk about the success of the series and what's next for it. They shared that the second season will only be nine episodes long and that as of now, they're most interested in reading all the fan theories about the show on Reddit. "Some of the fan theories online are amazing. Most are wrong, but I’ve read a few that are right or very close. Is it Reddit? Some of those people have figured stuff out based off of the chapter titles," Matt said.

They also shared that the series was greenlit for a second season before the first season came out, so they've been writing all summer long. "Even way back when we pitched to Netflix the first season, we talked about where it would potentially go. They understood the potential. Season one does almost feel like a big movie that comes to a sort of ending. A lot of that was based on the character of Will and the repercussions of him being in this upside down world for a week. Exploring that would be the second season. Once we got into the room for season two, we started expanding our mythology. We never got boxed in, because we’re dealing with an alternate dimension. It feels like the possibilities are limitless. We’re building up the mythology in a way that we know now where we want the story and these characters to end. We have more of a game plan now than we did two years ago," he said.
