'Stranger Things' Season 4 Premiere's Title Is an 'X-Men' Reference

“Stranger Things 4” may not hit your screens for a while — cards on the table, we actually have no idea when it will launch — but that doesn’t mean strange things aren’t happening behind the scenes to pull the upcoming episodes together.

On Wednesday, dubbed “Stranger Things Day” by Netflix, the Twitter account for the show’s writers’ room shared an image of the script for Episode 401, written by the Duffer Brothers themselves, revealing the premiere’s title: “Chapter One: The Hellfire Club.”

The tweet read, “looking for new members… are you in?”

OK, for those of you who don’t immediately get the reference, allow us to explain: The Hellfire Club is a fictional society featured in Marvel Comics that is often at odds with the X-Men. The group abducts Jean Grey, an X-Man with psychic abilities not unlike Eleven’s (Millie Bobby Brown), and try to use her as a weapon in their evil schemes.

Is it possible this is a hint that Season 4 will feature Eleven getting her powers back — and then being kidnapped by a group that wants to use them for their own nefarious purposes?

“Stranger Things” was renewed for a fourth season at Netflix in September, just as the streaming service signed the sci-fi series’ creators and showrunners, Matt and Ross Duffer a.k.a. The Duffer Brothers, to a multi-year film and series overall deal.

The Evolution of Sean Astin, From 'The Goonies' to 'Stranger Things' (Photos)

"The Goonies" (1985)

Astin's first film role was playing Mikey Walsh, the de facto leader of The Goonies, in the adventure classic. The character's signature exclamation of "Holy Mackenzie!" was an ad-lib by Astin, who wanted to sneak his brother's name into the movie.

"Encino Man" (1992)

Astin starred with Pauly Shore as a pair of geeky high schoolers who find a caveman (played by Brendan Fraser) in their backyard hidden in a block of ice. Despite negative critical response, the unabashedly silly movie was a success at the box office and amassed a cult following.

"Rudy" (1993)

In this 1993 tearjerker biopic, Astin portrayed Daniel "Rudy" Ruettiger, who lived his dream of playing football for the University of Notre Dame despite significant obstacles. After this role, Astin didn't have to prove nothin' to nobody about his acting chops.
TriStar Pictures
"The Lord of the Rings" film franchise (2001-2003)

Astin took on the role of Samwise Gamgee, patron saint of faithful sidekicks. The red-headed hobbit reminded Frodo and audiences everywhere that there was some good -- even with Sauron's minions on their tail -- and that it's worth fighting for.

"Stranger Things" (2017-2019)

Bob Newby is the manager at the local Hawkins RadioShack and (starting in Season 3) the love interest for Joyce Byers, played by Winona Ryder. Somehow, the kid from "Goonies" ended up going on a date with Lydia from "Beetlejuice," and all was right in the world.
