It's a blessing that I got to work on a film like 'Zero' with Shah Rukh Khan: Aanand L Rai

Be it Darr, Baazigar, Swades or Chak De! India, Shah Rukh Khan has taken some big risks in his over 25-year-long career and it was this "gutsy" attitude of the superstar that made filmmaker Aanand L Rai believe in him.The duo have collaborated for the first time on the upcoming film Zero and the director said Shah Rukh still has a lot to offer as an actor.
