Singapore– HBO Asia remembers Muhammad Ali with the HBO Original movie, Muhammad Ali’s Greatest Fight, now on HBO On Demand (StarHub TV Ch 602 / StarHub Go). Famous for both his signature shuffle and verbal sparring, boxer Cassius Clay quickly rose to fame in the ‘60s, becoming the world’s best-known athlete – and eventually its most controversial. After joining the Nation of Islam and adopting the name Muhammad Ali, he was widely denounced for refusing to be drafted into the U.S. military, based on his religious opposition to the Vietnam War.
