No network is wont to give up their biggest success, and Netflix can’t be thrilled with Stranger Things lasting four or five seasons. Well, there’s good news for them (and us), as the Duffer brothers say their four-season plan is likely to expand over time.

It wasn’t long after Netflix finally confirmed a second season for Stranger Things that the Duffers were heard to suggest their vision lasted four or five seasons. After all, things can only get so Strange in Hawkins, Indiana before the Byers pack up to leave town, but more recent chatter from series creators have suggested settling into a four-season idea. As Entertainment Weekly now reports, however, producer Shawn Levy believes the Duffers are still open to following the story, however many seasons it takes:

Hearts were heard breaking in Netflix headquarters when the Brothers made four seasons sound like an official end, and I was suddenly getting phone calls from our actors’ agents. The truth is we’re definitely going four seasons and there’s very much the possibility of a fifth. Beyond that, it becomes I think very unlikely.

At the very least, Ross Duffer corroborated that “It wasn’t intended to be a seven-season thing,” while Matt said Netflix (who also steered them way from an anthology approach) approved of a shorter run:

After it became successful, we had one of those big meetings with Netflix over dinner and they were like ‘We don’t want this going on that long.’ They were very supportive of it. It’s stupid to put an end date on it right now because we don’t know.

Hopefully Stranger Things 2 will give clearer account of the overall story in its October 27 release, so stay tuned.
