Anand, whose last film, "Chargesheet", was released in September, was in London with his son, Suneil, when he died on Saturday from a heart attack, aide Mohan Churiwala told Reuters.
"He was never sick. Even when I spoke to him last evening, he sounded fine - hale and hearty," Churiwala said.
Anand is also survived by his wife, Kalpana Karthik.
Born in Lahore, Anand travelled to Mumbai to work as a clerk in a government office in 1944 and got his first break two years later in the film "Hum Ek Hain". He turned director soon afterwards and went on to deliver a string of hits.
"CID", "Guide", "Hare Rama Hare Krishna" and "Jewel Thief" are movies considered part of Bollywood's essential viewing catalogue, and Anand's unique acting style is widely celebrated.
