"I'd never dare to compare David's and Sai Paranjpye's 'Chashme Buddoor'. I didn't think of Sai's film even once. There's no connection between the two. It has been a very liberating experience for me," said Siddharth, who made an impact with his role in "Rang De Basanti".
The actor is currently doing films in four languages - Tamil, Telugu, English and Hindi - and says "that's damn exciting for an actor who always complains about the quality of work offered to him".
"Would you believe it, Ravi Baswani and I went to the same college! Though he was much too senior for me to know him. But Ravi is very dear to me as an actor. I'm paying a homage to him," said Siddharth, who graduated from University of Delhi's Kirori Mal College.
Siddharth says he did "Chashme Buddoor" for a special reason.
"David and I have been meaning to work together for a while. While earlier projects didn't materialise, we became friends," he said.
The 33-year-old is also part of Deepa Mehta's "Midnight's Children".
"Luckily for me, within six months I got to work with Deepa Mehta (in 'Midnight's Children') and David. They are the two completely contrasting 'D' factors in my life.
"Both are so comfortable with the craft. I just had to go on both the sets and surrender myself to the director. While one was serious business, the other was fun all the way," he said.
