From The Godfather to The First Wives Club, Manhattan to Something’s Gotta Give, American screen siren Diane Keaton has charmed us with her self-effacing humor and pioneering fashion sense over the course of her illustrious 40-year career. Famously propelled into the role of Hollywood’s most influential dresser as Woody Allen’s flustered muse in Annie Hall (1977), Keaton became the hallmark of the 1970s tomboy look with her unmistakable Chaplin-esque bow ties, hats and oversize tailoring. Sporting offbeat strands of pearls, berets and turtlenecks, her megawatt personality drew the romantic attention of cinema’s leading men, including Warren Beatty and Al Pacino. These and other affairs were considered in-depth when Keaton put acting on hold to pen her critically acclaimed personal memoir Then Again. In 2012 she followed her debut authorial effort with Home, covering her passion for architecture and design. Next up is the onetime face of L’Oreal’s as-yet-untitled tome on “beauty, ageing and being a woman,” which will lend her views on our cultural obsession with youth and appearance. The Oscar-winning actress will also return to the big screen later this year with the The Big Wedding, a remake of the French film Mon frère se marie starring Hollywood greats Robert De Niro and Robin Williams. On her birthday, we raise a glass to this modern renaissance woman.
