Nicole Kidman says a great regret of her career was failing to call director Stanley Kubrick the night before he died. Kidman swooped into the New York Film Festival Wednesday as recipient of its first-ever tribute, then returned to the Paris set of “Grace of Monaco.” During a Q&A before a screening of her movie “The Paperboy” [See review in Pulse, Page 33], she recalled meeting Kubrick for the first time with ex Tom Cruise. “Tom and I went to his house and had dinner, and I remember I was nervous,” she said, adding she was ultimately “able to sit on the floor of his office . . . and be privy to so many things. It was like having a great, great teacher.” But Kidman never realized “Eyes Wide Shut” would be Kubrick’s last film. “I remember thinking [he] was frail, and . . . if I were more intuitive I would have realized that he was not well,” she said. “One of the worst things . . . was, I was going to call him [on Kubrick’s last night alive], and I didn’t. Instead I got a phone call [the next day] saying Stanley was dead. It was one of my great regrets that I didn’t call him that night.”
