The Hustler (2021)

Five contestants answer trivia together, but one secretly knows the answers and has to avoid making that advantage obvious. Craig Ferguson's conversational style lets an apparently incidental remark become something to reconsider. The compact, self-contained game is useful when you want The Traitors' pleasure of scrutinising a person without committing to another long elimination season. The final judgement depends on identifying the hidden player, not simply knowing more trivia.
