Pop Culture's Best Couples: 26 True (Fictional) Lovers

LANCELOT AND GUINEVERE
Le Morte d'Arthur
Not every great relationship is a healthy one. Take these two (pictured from 1981's Excalibur, played by Cherie Lunghi and Nicholas Clay), who got their medieval groove on despite the fact that she was married to King Arthur, who also happened to be Lancelot's most revered knight and best mate. And their inability to keep their paws off of each other is pretty much what brought an end to the glory days of Camelot. Ah, sweet, sweet lust. —Marc Bernardin
