"Return to Downtown Abbey," No. 2
PBS: 9 p.m. EST Sunday, Dec. 1 (check local listings)
In the run-up to the premiere of season four of the international hit drama "Downton Abbey" on Sunday, Jan. 5, PBS is airing a special that recaps the first three seasons and previews the new one. Get ready to experience the Roaring '20s. Without fundraising breaks, this preview lasts about an hour. I have a feeling this preshow will be used as a PBS fundraiser again (as they did last year) and will wander into the 90-minute/two-hour zone, so you might want to set your DVRs.
