Apparently, at least three more stars of the Netflix universe Mike Flanagan will appear in extremely short cameos in the new series. Based on Netflix loved, famous stars Kate Siegel, Hamish Linklater, and Carla Gugino all appear in “The Midnight Club,” albeit in obviously very minor ways. Linklater is of course Father Paul on “Midnight Mass,” while Siegel has played Theo Crane, Viola, Perdita’s sister, and Erin Greene in previous Flanagan shows. Gugino, meanwhile, has appeared as the Narrator in “The Haunting of Bly Manor” and played Olivia Crane in “Hill House”. While I don’t want to spoil all the fun (and I still haven’t found one of these cameos), I will say it’s worth keeping an eye on a TV-watching character in the second half of the series.
