Zach Galifianakis

Zachary "Zach" Galifianakis (born October 1, 1969) is an American actor, comedian, and producer known for his distinctive comedic voice and willingness to embrace unconventional and absurdist humor. He achieved mainstream success with his memorable role as the eccentric and unpredictable Alan Garner in Todd Phillips' The Hangover (2009), which became a cultural phenomenon and grossed over $460 million worldwide. Galifianakis' performance, characterized by his deadpan delivery and physical comedy, made him a household name and led to numerous film roles in both comedies and dramas. Beyond acting, he is renowned for his stand-up comedy, which is intentionally awkward, surreal, and often deliberately anti-audience in its approach—a style that has influenced contemporary comedy. He also created and starred in the acclaimed Comedy Central series Between Two Ferns, featuring his dry, uncomfortable interview style. His production company, Funny or Die collaborations, and diverse film choices have established him as a creative force in entertainment who consistently pushes comedic boundaries.
