The Devil's in the Details of "Family Guy"'s Latest Special The latest announcement from the "Family Guy" camp is that Kieran Culkin will play Satan in an upcoming Halloween themed special, simply titled "Happy Hell o ween".
This news raises eyebrows, particularly given Culkin's previous role as Roman Roy on HBO's "Succession", where he played a rather unsavory character.
However, the casting choice seems to be more about poking fun at the idea of the devil than taking Satanology seriously.
