Christopher Lloyd joins “Wednesday” Season 2 as Professor Orloff, the oldest and strictest teacher at Nevermore. The casting marks a return to the Addams Family universe for Lloyd, as he previously played Uncle Fester in the 1991 film “The Addams Family” and reprised the role in 1993’s “Addams Family Values.”

The show, which premiered on August 6, is the Addams Family spinoff that continues the tale of Wednesday Addams at Nevermore Academy.

By the second episode we learn that the stalker is none other than Agnes (Evie Templeton), whose obsession with Wednesday began the previous year at Nevermore Academy after she saved the school from a demon at the end of season one.
