Mumbai, April 13 (IANS): Veteran actor Prem Chopra has launched his biography titled "Prem Naam Hai Mera" penned by his daughter Rakita Nanda.

"I always thought how is this possible what you want to write. This is my normal life, what you want to write? She was interested to write and she did. She went to my friends with whoever I have worked...," Prem told reporters here at the unveiling of his biography Saturday evening.

Nanda shared how she decided to write a biography on her father, popular for playing negative roles in films like "Teesri Manzil", "Woh Kaun Thi", "Do Raaste" and "Kati Patang".

"It started with a conversation I had with my husband Rahul. He said we were celebrating 100 years of Indian cinema and your father has been in the industry for 50 years... that should be an interesting read. That's how it started," she said.

"I spoke to my dad and he was game. Movie by movie we went through. I was dealing with every generation of actors - Dilip Saab (Dilip Kumar), Amitabh Bachchan - for the biography... My mom has chronicled all the clippings for past 45 years and that was a big help," she added.

Many celebrities made their appearance at the event - among them Amitabh Bachchan, Manoj Kumar, Akshay Kumar, Sharman Joshi and Vidhu Vinod Chopra.
