At Bombay Talkies studio, Rai partnered with
Sashadhar Mukherjee, and Mukherjee's brother in law
Ashok Kumar, worked as a technician in the studio. Due to suspected romantic liaisons between his wife Devika Rani and the leading man, Najmul Hasan, in
Jeevan Naiya, Himanshu sacked the leading man and cast the gawky and reluctant Ashok Kumar as the leading man. Kumar went on to have a successful career in films. After Rai's death, there was a struggle for studio control. His widow Devika Rani was in conflict with Sashadhar Mukherjee. Eventually there was dual control and alternate production of films by the two camps. During this era Mukherjee produced the studio's biggest hit
Kismet in 1943. Then Mukherjee broke away to form
Filmistan Studio in partnership, and Devika Rani, fully in charge of the studio, did not have as much success. In 1945, Devika Rani married
Svetoslav Roerich and moved away from Bombay and films. Ashok Kumar and Mukherjee made a bid to revive Bombay talkies and produced one big hit in
Mahal. Eventually, the studio shut down and is now a decrepit property in
Malad. ==Filmography==
