Ghostshas a fairly expansive cast with ten main players in the weekly ensemble and a growing Rolodex of regular guest stars that features comedy icons like Punam Patel as Jay’s (Utkarsh Ambudkar) sister Bela, Caroline Aaron as Pete’s (Richie Moriarty) ex-wife Carol, and Tristan D. Lalla as everyone’s favorite contractor/Hudson Valley player Mark. We’ve been seeing more and more of these friendly faces in Season 4, so when I sat down with series star Rose McIverto discuss her directorial debut on the series, I had to know if she had anyone in mind as a dream guest star for Ghosts. Offering up my own answer, I suggested the legendary Catherine O’Hara(Schitt’s Creek) as a Gilded Age-era Farnsby, to which McIver happily agreed, saying, “Oh, that’s brilliant! You should work in casting. That’s so good. She’d be brilliant in that. Now that you say that, she’s definitely a choice.”
