At eight, Sean Connery saved him from drowning. At thirteen, he attended his Aunt Joan Didion and Uncle John Gregory Dunne’s legendary LA launch party for Tom Wolfe’s The Electric Kool-Aid Acid Test. In his early twenties, he shared a Manhattan apartment with his best friend and soulmate Carrie Fisher. A few years later, he produced and starred in Scorsese’s After Hours. Amidst it all, Griffin’s sister Dominique, just 22 and a rising star in Hollywood, was brutally murdered by her ex-boyfriend, leading to one of the most infamous public trials of the 1980s, which also marked the beginning of their father Dominick Dunne’s celebrated writing career. And yet—as GRIFFIN DUNNE will tell journalist and author TODD S. PURDUM—for all its boldface characters and jaw-dropping scenes, his extraordinary life has always been a story about family.
