According to sources, Gupta doesn"t want Vidya to meet Sabrina because he believes that she would then pick up the latter"s mannerisms and replicate Sabrina"s actions when filming. He wants her to do the role in a different manner.
Kareena Kapoor had been approached for playing Jessica Lal"s role. However, she turned the offer down and now a newcomer will be doing it. Rani Mukherjee also has an important role in the film.
