School Spirits Season 4: Milo Manheim and Jennifer Tilly Return, Maria Dizzia Promoted

Milo Manheim will return as Wally Clark in Season 4 of "School Spirits," Paramount+ has confirmed, ending months of fan speculation about his future on the show. Jennifer Tilly also returns as Deborah Hunter-Price, and Maria Dizzia has been promoted to series regular as Sandra Nears.

Manheim's status had been the open question. Fans debated whether his commitment to Disney's live-action "Tangled" adaptation would push him out of the ghost drama entirely. It won't. How many episodes he'll actually appear in remains undecided, per the network.

The casting history is straightforward. Tilly joined in Season 3. Dizzia has been there since the first season, which makes her promotion less a surprise than a formal acknowledgment of tenure.

Who are the four new guest stars?

Season 4 adds Christian Weissmann ("Saved by the Bell," "Dear White People"), Clara Alexandrova ("Bet"), Katharine Isabelle ("Yaga," "The Order") and Briana Buckmaster ("Supernatural," "The Irrational") in guest roles. Paramount+ has released character descriptions:

• Weissmann plays Emmett, a vlogger claiming paranormal expertise who invents amateur "ghost tech." He's charming, kind, and — as an outsider whose methods don't always add up — possibly untrustworthy.
• Alexandrova plays Izzy, a rebellious girl from a neighboring high school working the counter at the local record store.
• Isabelle plays Tonya Terravina, a mysterious figure from Split River's past. She's described as wise, resourceful and fiercely independent, offering a new perspective on the show's supernatural world.
• Buckmaster plays Alex Grey, a determined reporter convinced Split River is hiding more than anyone admits.

A vlogger, a rebel, a ghost from the past and a reporter. If Season 4 plans to blow the town's secrets open, the casting sheet telegraphs it.

What is the show, and who runs it?

"School Spirits" is currently in production in Canada. The supernatural drama adapts the graphic novel of the same name and follows a group of teenage ghosts haunting a high school in Wisconsin.

Peyton List leads the ensemble, alongside Kristian Ventura, Spencer MacPherson, Kiara Pichardo, Sarah Yarkin, Nick Pugliese, Rainbow Wedell, Josh Zuckerman, Ci Hang Ma, Miles Elliot, Dizzia and Manheim.

Nate Trinrud and Megan Trinrud created the series and serve as co-showrunners and executive producers. List also executive produces. Paramount Television Studios produces, with Paramount Global Content Distribution handling sales.

No premiere date yet. With production underway in Canada and the cast locked, an announcement on Season 4's release window — and on Manheim's episode count — should be the next disclosure.
