The cast of Stranger Things is going to get even bigger in season 4. It's come to light that Netflix is looking to bolster the ensemble with four new characters that are poised to enter the fold in the upcoming season. While much remains mysterious regarding the show's return, as is customary, we do have some details on who these new characters will be, at least in vague terms, which could clue us into how they factor into the overall story.

According to a new report, four new male cast members are set to enter the hit sci-fi series. The Duffer Brothers and Netflix haven't confirmed the news publicly as of yet and, since production hasn't gotten underway just yet, things could change. That said, the report states that three of the roles will be teenagers, with the remaining one being an adult. None of the characters have been given names quite yet, and no specific actors have been named in respect to any of these new roles.

As far as the descriptions go, the teens are described as follows; one is a metalhead, one is an entitled jock and the third is said to sound an awful lot like Jeff Spicoli from Fast Times at Ridgemont High. The character in question was played by a young Sean Penn in the 1982 comedy classic. Given that Stranger Things hinges largely on 80s nostalgia, that seems to check out. The metalhead angle is also interesting, as this was in many ways a golden age for metal, with Metallica, Megadeath, Slayer, Anthrax and near countless other bands going strong at the time. The adult is far more mysterious, but the report suggests he'll factor into a storyline taking place far away from Hawkins, Indiana.

To that end, Netflix released a teaser for season 4 back in September that came with the tagline, "We're not in Hawkins anymore." That relates to a couple of things, it would seem. For one, Will's family moved to a new town, so he'll be off somewhere new. There's also the matter of David Harbour's Hopper, which is a subject of debate amongst fans, but there's evidence Hopper could be alive in a Russian prison somewhere.

The series cast includes Winona Ryder, Finn Wolfhard, Millie Bobby Brown, Gaten Matarazzo, Caleb McLaughlin, Noah Schnapp, Sadie Sink, Natalia Dyer, Charlie Heaton, Joe Keery, Dacre Montgomery, Maya Hawke, Priah Ferguson, and Cara Buono. Production on season 4 is set to begin in January 2020. The new season will consist of 8 episodes, which is on par with other seasons. Season 2 ran a bit longer with nine episodes. While Netflix has yet to set a return date for Stranger Things, a 2020 return is highly unlikely. Most likely, we'll see the show return in 2021. We'll be sure to keep you posted as further details are made available. This news comes to us via TV Line.
