If You Are Attending the PaleyFest Hannibal Panel

erinescence:

You can begin to pick up your tickets from the box office at 7:30PM.  Paley won’t begin seating people until around 8:00PM, as they need to clear the attendees from the Gotham panel that runs just before the Hannibal Panel before they can seat us. 

I called the Paley Center and they advise that if your tickets are for the main theater (not the overflow viewing room),  you should plan to arrive by 8:00PM.  They may begin seating for the overflow room a little earlier.
