Nicole Kidman and Tom Cruise - Days of Thunder (1990)
After seeing Kidman in 'Dead Calm,' Cruise flew her in from Australia for her American movie debut. By film's end, Cruise had left real-life wife Mimi Rogers in the dust and was igniting headlines with Kidman. The couple married on Christmas Eve 1990, adopted two children and separated -- amid much mystery -- just before their 10th anniversary.
