It's tempting to chart the evolution of Tom Cruise and Nicole Kidman's relationship through the three movies they made together. First, in 1990's hormone-fueled race-car movie 'Days of Thunder,' there's nothing but lust. Pure primal attraction. Then, in 1992's underrated immigrant flop 'Far and Away,' in which Cruise plays an Irish sharecropper in love with Kidman as the landlord's daughter, came romance—a love based on friendship, affection, and respect. And finally, with 1999's 'Eyes Wide Shut,' their burnt-out married couple find that their relationship, with no clear path how to proceed, has hit a dead end. 18 months after their final film's release, they split up in real life. Key Film: 'Eyes Wide Shut,' one of the best films of the '90s.
