No idea yet what characters they'll be playing in the follow-up to "The Young Pope," but it's a good guess Manson -- who looks pretty much like he always does -- isn't playing a man of the cloth.

This is the first time either will work with the series' creator, Paolo Sorrentino.
The series debuted on HBO in January 2017, earning Law a Golden Globe nomination. No air date has been announced for "The New Pope."
Manson's previous acting credits include roles on "Salem" and "Sons of Anarchy."
