Pierce Brosnan was in a romantic mood at a Cinema Society and Disaronno-sponsored premiere of his new film, “Love Is All You Need.” The ex-James Bond was spotted walking hand-in-hand with his wife, Keely Shaye Smith. “It was captivating,” he recalled of first meeting her in Mexico, when she was on assignment for “Today.” “After 19 years, we’re still going.” He added of his ongoing status as a sex symbol: “A sex symbol on the cusp of 60 . . . long may it last. It’s fun, but it’s all an illusion.”
