Was: Ben Linus, the meek-looking yet manipulative leader of the Others, who was happiest when he was in complete control of the island.
Is: Harold Finch, the engineer who built the “Big Brother” surveillance machine on CBS’ Person of Interest. He follows up on cases that his terrorism-focused program deems irrelevant.
Lost flashback quotient: Finch is just as secretive as Ben. Finch uses a crutch; Ben was briefly in a wheelchair after spinal cancer surgery in Season 3. One of his persons of interest was played by Alan Dale, who portrayed Ben’s nemesis, Charles Widmore. And where does Finch live? On an island (Manhattan).
