One of Hollywood's most enduring love stories fittingly reads like ... a Hollywood love story. They met on-set – the 1985 flick Volunteers – but alas, he was married.

"I didn't know what being in love was until I met Tom," Wilson has told Vanity Fair. Hanks similarly explained their courtship to PEOPLE: "When you find [love], it's undeniable."

KEVIN & KYRA, 21 YEARS
It's family first for the couple, who make it a point not to work on different movies at the same time. Or better yet, they costar in the same films, as they did with Pyrates and The Woodsman. Supporting each other career-wise is key, Sedgwick, 44, explains to PEOPLE. "We have our priorities straight, but we also know that work is really important to us," she said. "It's very important for me that I support him in his work and vice versa."

Married for longer than the combined ages of the Olsen twins, Newman and Woodward, (who met in 1952 while performing in the Broadway play Picnic) were the envy of their peers. So what was the secret?
