#2: Famous Siblings

Beatty’s older sister, Shirley MacLaine, was a trailblazer in their family. She first pursued a career in Hollywood, moving to New York to become a Broadway performer before transitioning into films. Her early success inspired Warren, though he initially avoided following in her footsteps too quickly.

Shirley’s work in major films of the 1950s, including The Apartment (1960), proved to him that acting was a viable career. Though the siblings pursued different acting styles, they remained close over the years, with MacLaine often teasing Warren about his legendary status as Hollywood’s most eligible bachelor.
