The two leads who play Claire and Jamie, Caitriona Balfe and Sam Heughan, are both relatively unknown, but that works to their advantage. They each embody their characters, and neither of them is an easy one (Claire is an unwitting time-traveler; Jamie's an authentic 18th-century Scottish warrior). In particular, Balfe handles Claire's bewilderment with the requisite complexity, and Heughan makes Jamie tough, sensitive, and very sexy. I know it might be hard to tell in the photos, but trust me — Heughan is pretty scorching under that tartan (and frequently shirtless).
