DOWNTON ABBEY REVISITED
PBS, 8:00 p.m. ET
Season 3 of Downton Abbey, featuring Shirley MacLaine, doesn’t premiere until next year – okay, January 6, but still, it’s a wait. In the meantime, here’s a new special, a retrospective that will remind fans what we’ve been missing, and initiate newcomers to what’s about to come. Angela Lansbury hosts. Check local listings.
