Philip Pine and Philip Pine in The Outer Limits: The 100 Days of the Dragon, a Manchurian Candidate-influenced episode with impostors from a foreign nation placed into the highest levels of American government.
I remember, Melakon, not expecting to like that episode for some reason. But it turned out to be pretty good!
I was a bit bugged, though, ironically by the episode from which your avatar derives its existence. It's enjoyable...but I was distracted by the casting of Skip Homeier and Keith Andes as brothers' in law. They are just too suited to play full brothers!
