Mukherjee is survived by actor-wife Tanuja, daughters Kajol and Tanisha. Sources said Mukherji was unwell for quite some time and had to be hospitalised as well. He breathed his last at 0820 hrs at home.
The funeral will take place at the Santacruz crematorium at 1400 hrs, sources added. Mukherji's passing away on the eve of the release of `U Me aur Hum', the directorial debut of his son-in-law Ajay Devgan, casted a pall of gloom in the family.
Family sources said the film will be released as per the schedule. Devgan had not organised a premiere for the film on Thursday.
Shomu, youngest son of late Sashidhar Mukherji, founder of the Filmalaya studios was a producer-director of films like Ek Baar Muskura Do (1972), Nanha Shikhari (1973), Chaila Babu (1977), Fifty Fifty (1981), Pathar Ke Insan (1990) and Sangdil Sanam (1994).
His other siblings Joy and Deb Mukherji were actors.
