The biopic of independent-minded, controversial Christina, queen of 17th century Sweden, paired Garbo with popular silent-screen actor John Gilbert (her former fiancee and co-star was also purported to have been her passionate, off-screen lover). Although Gilbert's career star was fading, Garbo insisted that he play the male lead role (although Laurence Olivier had been the original choice). The plot, ending with the Queen's abdication from her kingdom and self-imposed exile and withdrawal (for the ill-fated love of a Spanish nobleman-envoy), in order to follow her heart to Spain (to return her slain lover to his homeland), prophetically echoed the same sort of conflict that Garbo struggled with in her private life.
