Stranger Things 4 is reportedly looking to cast four new roles for the upcoming season.

Sources recently confirmed to TVLine that series creators the Duffer Brothers are searching for four male actors to fulfill the recurring roles – three of which are said to be teenagers and one of which is apparently an adult character.

The outlet describes the three adolescent characters as a "metalhead," an "entitled jock," and a doppelgänger of "stoner" Jeff Spicoli from Fast Times at Ridgemont High, while the adult member of the group is said to possess characteristics that indicate he will factor into a storyline that takes place outside of Hawkins, Indiana.

Given the far-off location, there is a chance this older cast member could have some involvement in the fate of Chief Jim Hopper, as a season three post-credits scene hinted the fan-favourite character might have been captured and thrown inside a foreign prison after possibly surviving the blast caused by the Russians.

A representative from Netflix declined to comment on the report.

Since production on the new season has not yet started, there is a possibility these new characters might be altered or scrapped entirely before shooting begins. Season four of the hit Netflix show is not expected to wrap filming until August next year, meaning new episodes will not premiere until sometime after summer 2020.
