His agent, Steven Kenis, said the legendary Egyptian-born actor, who had been suffering from Alzheimer's disease, had a heart attack in Cairo.
Sharif became an international heartthrob and movie star after starring in the David Lean classics Lawrence of Arabia and Doctor Zhivago. He won Golden Globes for both films and nabbed an Oscar nomination for his supporting role in Lawrence as Sherif Ali.
Sharif made one of cinema's best entrances in Lawrence — a lone, ominous figure galloping toward Lawrence (Peter O'Toole) on a camel for nearly two minutes and killing Lawrence's guide Tafas (Zia Mohyeddin) with a musket shot in the process, as the two slowly realized the mirage was actually real.
Sharif's career thrived in the 1960s, as he appeared in The Fall of the Roman Empire, Genghis Khan, The Night of the Generals, More Than a Miracle and Funny Girl. However, as time went on Sharif began to lose interest in acting, which he blames on having starred in various "bad" movies. By the '90s, he was putting most of his energy towards playing bridge, a card game in which he was once ranked as one of the 50 best players in the world.
But by 2004, Sharif quit bridge too, along with his womanizing ways. "The reason I quit is because I wasn't as good as I used to be," Sharif told The Guardian at the time. "And now it's the same thing with girls, so why the aggravation?"
Sharif is survived by his son Tarek, an illegitimate son from whom he was estranged, and two grandchildren.
