After graduating in comercial arts from Mumbai University, he started as a publicity designer in films.
Shah first assisted Karan Johar in Kabhi Khushi Kabhi Gham and later Ramgopal Varma in Bhoot. And for someone who believes in the Ramgopal Varma school of film-making more, getting a toehold in Johars production company and having Shah Rukh Khan to co-produce it was a miracle. I give full credit to Karan Johar for this film because he gave me 200 % freedom to make it. He never interfered in my work. I had assisted Karan in Kabhi Khushi Kabhie Gham and found that the production controller always needed stuff like the puja thali and flowers. So when I asked for 25 litres of blood for a shot in my film, everyone was shocked. We got all things that one would never see in Dharma Productions: Tigers, jungles and blood. Everyone liked this experiment as I was making a different kind of a film.
Luckily for Shah, being different paid off rich dividends, as this songless thriller (if you discount the title track and the last song as the credits roll by) turned out to be among the years top five hits. In 2006, Shah scripts his next film and if things turn right then Johar will produce this one too!
