Now we know that the episode will be inspired by The Breakfast Club, called "The Midnight Club". Even the OG Anthony Michael Hall from Breakfast Club will join the episode, playing the Principal Featherhead.
Just look at the yearbook photo where they've used real pics of the cast:
In a description of the episode, it's been revealed that Featherhead "gets caught up in the game the teenagers are playing in an unexpected way."
Can we just appreciate the superlatives that they've added onto the characters? Hiram gets "most likely to succeed (illegally)," Fred Andrews was voted "most likely to never leave Riverdale", Penelope Blossom got selected as "most likely to snitch," and Hermione Gomez was voted "most likely to marry rich."
The episode will air on November 7!!
