Not true actually. Divya Bharti acted in a dozen Hindi films in just the year 1992–93 including 10 hindi films in 1992 (In Bollywood the record is hold by Reena Roy who had 13 releases in 1982).
Out of those 10 hindi films in 1992
Deewana Superhit
Shola aur Shabnam Superhit
Vishwatma Above Average
Balwan Above Average
Dil hi Dil me Disaster
Dil ka Kya kasoor Disaster
Dil Aashna hai Flop
Dushman Zamana Disaster
Geet Flop
Jaan se Pyara Average
So she had 4 hits out of 10 in 1992. She also had 2 releases in South making her total films in 1992 to 12.
In 1993 she had 3 more releases before her unfortunate d**th. She could have done many more films but couldn't and those roles were passed on to others like Mohra, Laadla, Vijay path etc. Her 1993 releases include
Kshatriya Below Average
Shatranj Flop
Rang Superhit
In total she delievered 5 successful films in Hindi cinema out of 13 total films. This is not really a record as Reena Roy had 8 successes inn1982 and Hema Malini had an unbroken streak of 9 hits. But Divya Bharti was an exceptional talent which was cut short.
