Tom Cruise spoke publicly about his ex-wife Nicole Kidman to Vanity Fair in 2002, just a year after the former couple’s divorce, and hasn’t said much since. At the time, the magazine asked Cruise why he and Kidman had split, and the “Mission: Impossible” star responded vaguely, insisting twice to the outlet that Kidman “knows why.”

Eyes Wide Shut centers on Dr. Bill Harford, who is shocked when his wife, Alice, tells him that she contemplated having an affair the previous summer. He then embarks on a bizarre, night-long odyssey in New York City, during which he infiltrates a masked orgy of a secret society. It was Kubrick’s final film before he died in 1999 at age 70.

Eyes Wide Shut came out in 1999, and it was only a few years later, in 2001, that Tom and Nicole announced their separation. The couple’s divorce has been the subject of pop culture lore for decades, and to this day, it isn’t known exactly why they broke up.
