Stranger Things has added another new cast member for its upcoming second season. According to The Hollywood Reporter, Brett Gelman (Eagleheart, Married) is joining the cast and will play the new character Murray Bauman. He’s a disgraced journalist who is now a conspiracy theorist investigating a cold case in the show’s fictional setting of Hawkins, Indiana.

That’s a lot to chew on, as it’s unclear what that cold case is and what connection it could have to the events of Season 2. Given that Season 2 is set just one year after Season 1, the cold case that Bauman is looking into would likely be something that happened before the first season’s timeline.

Gelman, who will also appear in Showtime’s Twin Peaks revival, is just the latest to come aboard for Stranger Things Season 2, as previously confirmed new cast members include Sean Astin (The Lord of the Rings) and Paul Reiser (Aliens). Additionally, Danish actress Linnea Berthelsen and actors from Power Rangers and American Odyssey are joining.

Stranger Things Season 2 is scheduled to come out sometime in 2017. According to creators Matt and Ross Duffer, Season 2 will be “darker and weirder” than the first season. Producer and director Shawn Levy recently teased that Season 2’s plot will be partly about the characters trying to find a sense of normalcy after the traumatic events of Season 1–and that might not be possible.

In other news, it’s been confirmed that Millie Bobby Brown’s character, Eleven, is coming back for Season 2.
