Filmistan Studios founder Sashadhar Mukherjee's youngest son Shomu, who died Thursday, was perhaps the least known of three Bollywood brothers. Even in death, he was remembered best as Kajol's father and Tanuja's estranged husband.

Shomu, who died of a heart attack, had been unwell for quite a while, said a former associate.

Shomu's elder brothers Joy and Deb tried their luck in acting. Shomu was always more interested in production and direction.

"Ek Baar Muskara Do" was his first film as a producer. Made in 1972, it starred his older brothers and Tanuja. Shomu's whirlwind romance with Tanuja during the making of the film culminated in marriage in 1973. They had two children Kajol and Tanisha.

In 1973, Shomu made his directorial debut with ""Nanha Shikhari", but it didn't do well. After that he churned out quite a few films - "Chaila Babu", "Fifty Fifty" and "Pathar Ke Insan" - but could not replicate his father's success.

In 1994 Shomu produced and directed his last film, "Sang Dil Sanam", starring Salman Khan and Manisha Koirala. Once again, it didn't do well, and Shomu stopped making films.

Shomu, who had been living alone, died a day before son-in-law Ajay Devgun released made his directorial debut with "U, Me Aur Hum".

The affection of the entire Hindi film industry for Shomu was reflected in the way everyone from Ashutosh Gowariker to Karan Johar to Rani Mukerjee came to condole his family.
