Kangana said though she had a conversation with Rangoli on making such movie but the latter was not excited.
"I told her I want to make a story on you. I want the rights of your life. I want to play you, me, everyone. She said yes it will be a very big flop film," Kangana told reporters.
The actress was speaking at the new cover launch of Femina magazine.
"On a serious note, I think her (Rangoli's) life is far more interesting than my life, thanks to her husband who has been madly in love with her since day one. My life is not as exciting as Rangoli," Kangana added.
Rangoli narrated her struggle since a man flung acid on her and the impact the incident had on her life.
"I was struggling for my life. When acid goes deep inside your skin and if you're not treated on time, it attacks your organs also. When the incident happened, I was struggling for my life...the psychological problems, the scar problems, was not on mind," she said.
Rangoli recalled the physical pain and mental trauma she underwent after the attack.
"My sister was there who inspired me. I am more confident today than I was before the acid attack. I know my strengths and weakness. My accident has taught me a lot," she said.
Kangana, who has acted in women-oriented films like 'Queen' and 'Tanu Weds Manu Returns', feels the perception about heroes in society needs to be changed.
"I always say the guy who threw acid on Rangoli and people who do things like that, they think it's very heroic.
Their idea of heroism comes from movies and this sort of stalker, excessive lover is hugely inspired from films. These rejected boys identify themselves a lot with tragic characters. We need to change perception of heroes," she said.
Rangoli, who manages the work of her sister, has expressed her desire to start a production house.
"Right now I am managing Kangana. But I have bigger goals. I would like to produce a film and Kangana will direct it," she added.
