The Duffer Brothers have revealed new information about Stranger Things season 2. The brother directing duo admits that the second season will probably jump a year ahead. Here is an excerpt from their interview with
IGN:
Matt: Yeah, you have to do the Harry Potter thing. You have to jump a year. Because like Gaten [Matarazzo], his voice has already dropped quite a bit, to the point where we couldn’t even do ADR with him. We had to pitch it way up. It’s dropped. He’s grown. As much as I would love to have it be Christmas right after that, it’s just not feasible, so we’re going to skip a year. They’ll be a year older and all their changes they’re going through, we’ll take that into account and kind of work that into the show.
Ross: It’s also just exciting having these initial conversations about it because the jump allows us to say “what happened in that year?” It actually opens up a lot more storytelling possibilities. These characters have changed and the audience has to sort of fill in those gaps of what went on in that year. To us, it’s exciting. So the fact that we have to make this jump, because of the kids, we’re trying to use that to our advantage. … And how have these characters moved on with their lives and not just in the plot and supernatural [aspect] but also just in terms of their characters and what have they done to fill that time?
Matt: We like that they’ve all had a very traumatic, nightmare experience together and after it’s over they kind of try to sweep it all under the rug. Season 2 would be very differently, structurally. It would be that everything seems great on the surface, and then there are hints that things aren’t okay or that there are lingering effects from what happened last year. The initial instinct is to push that back and sweep that crap back under the rug but eventually it becomes impossible to ignore and so they have to confront the repercussions of everything they’ve experienced. I like to think about Stephen King’s It too. — that’s a big time jump. They jump like thirty years. But the idea that the evil is still there and comes back to haunt them and one of the characters finds out about it and kills themselves immediately. That image always stuck with me.
I mean it has all the elements for a great show but it seems so "safe" and boring. Hopefully it will get more interesting towards the end
