The filmmaker Sheetal Talwar is taking his time in casting the actors for his next project: a biopic of the former Indian prime minister Rajiv Gandhi. "As far as the star cast of the film is concerned, obviously we have our wish list, but we can't talk about it right now," said the producer Talwar. "A lot of research is going on and we are putting together all other things. So basically, the hunt is still on and we are looking for the appropriate actors who can portray the roles well." "It's not just Sonia Gandhi, but each and every role is very tough to cast. All the characters in this film have a major contribution in this story. It's not about Indian or foreigner, we are just looking at the right actress who can pull off Sonia Gandhi's role in the film," said Talwar. The project is currently in the script-development phase and filming is expected to start in the middle of next year. It will be the first directorial venture for Talwar's wife Bhanva. "It is a story about the vision of a man. We have to capture the lifetime of a leader whose vision has taken our country ahead. We are celebrating the vision of a man and his journey," said Talwar. Rajiv Gandi led India from 1984 to 1989 following the assassination of his mother Indira Gandhi, who was the prime minister at the time. He was killed while campaigning for reelection in 1991. - IANS
