Mirza, who turned 28 on Saturday, said she is very guarded about her personal life and that's the reason she recently rejected a director, who approached her for a biopic.
"I don't want a film to be made on me. I am a very private person and I don't like to share my intimate details with people and then have a film made on it. I have been approached by filmmakers and very recently I rejected a film as well," said Mirza on the sidelines of National Children's Film Festival.
"But you never know I may have a change of heart in future. But if you ask me who I would like to play me on-screen, I would say Deepika Padukone," she said.
In recent years several films have been made on the life of sportsmen - Paan Singh Tomar, Bhaag Milkha Bhaag (based on athlete Milkha Singh) and the latest Mary Kom on the life of the Olympic medal winning boxer.
Mirza, who is married to Pakistani cricketer Shoiab Mallik, is currently busy with her autobiography, tentatively titled Against All Odds and has already finished writing 26 chapters. [Is Sachin Tendulkar's take on Greg Chappel a Marekting Gimmick?]

"Whatever details I am comfortable with; I have shared it in my book. All that people want to know about me will be more or less answered in the book. Till now I have detailed my life till the year 2012. We are still planning a few more chapters," Mirza said.
