JULIANNE MOORE & BART FREUNDLICH

The actress, 61, and the director, 52, tried to ignore their feelings when they met on the set of 1997’s The Myth of Fingerprints. “I remember looking at myself in the mirror and thinking, ‘Don’t even think about doing this,’” Bart later said. Meanwhile, Julianne grappled with the gap in their ages. “It was a huge difference! He was 26 and I was 35!” she recalled. “But he seemed much older than his years, and age evaporated over time.”
