An acclaimed actor and director, Anand's career spanned more than six decades and dozens of films, earning him scores of national film awards, and a reputation as a evergreen, flamboyant romantic hero.
He was in London for a check-up when he suffered a cardiac arrest and died late Saturday, IANS news agency quoted his manager Mohan Churiwala as saying.
The iconic star is survived by his wife, former actress Kalpana Karthik, a son and a daughter.
He was working on a US-produced musical love story at the time of his death, titled Song of Life. Anand was playing the lead alongside a US cast.
Condolences poured in for the star from India's president and prime minister as well as fellow Bollywood stars.
"An era has come to an end. Dev Anand leaves a void never perhaps to be filled again," Bollywood actor Amitabh Bachchan said on the micro-blogging website Twitter.//DPA
