Cary Elwes has just joined the cast of Netflix's Stranger Things, but he's already turning the third season upside-down with his social media savvy.

Shortly after it was announced that he would join the Hawkins, Indiana crew in an official capacity — to quote him, "there's a new mayor in town" — he decided to offer up a glimpse of himself and now-co-star Joe Keery (who plays Steve "The Hair" Harrington, of course) posing for a Polaroid in true '80s fashion.

Elwes, who'll forever be associated with era favorite The Princess Bride, was among several actors to be added to the call list for Season 3, including Jake Busey and Maya Hawke. It remains to be seen whether the new season acknowledges that piece of pop culture coincidence or not, but it'd be surprising of the Duffers to pass up the opportunity.

Regardless, it's a good thing the town does have some new leadership on the way. After the second season exposed an elaborate tunnel system — a literal wormhole — full of terrors that connected Hawkins to the upside-down, Eleven (Millie Bobby Brown) was able to shut it down. However, the last frame of the season revealed that their troubles are nowhere near from over. The mega-monster that infected Will Byers' (Noah Schnapp) mind so well is nothing compared to the creature that haunts the place in secret now. Yikes.

Also ... could this mean that Steve's new career path is gonna be in politics somehow? That would be a twist.

Stranger Things Season 3 is expected to premiere in 2019.
