THE IRON LADY
Showtime, 8:00 p.m. ET
Meryl Streep earned Oscar Number Three, and her first in decades, by portraying British Prime Minister Margaret Thatcher in this 2011 film biography. Its framing device, a mixture of flashbacks and ghostly visitations, is a bit unusual, but Streep’s impersonation is ghostly, too: less acting than channeling. Jim Broadbent co-stars.
