Donald O’Connor

Donald O’Connor (August 28, 1925 – September 27, 2003) was a dynamic American dancer, singer, and actor, a quintessential triple-threat entertainer whose boundless energy and acrobatic style made him a beloved Hollywood star. He came to fame in the 1940s at Universal Pictures, starring in a series of popular musicals and comedies, including the wildly successful Francis the Talking Mule films. Despite a long and varied career, O’Connor is immortalized by his spectacular performance as Cosmo Brown in the classic musical Singin’ in the Rain (1952), where his comedic and athletic genius is perfectly captured in the legendary show-stopping number, “Make ‘Em Laugh.”
