Farhan Akhtar, whose latest release, Bhaag Milkha Bhaag, recently made it to the Rs100 crore club, feels its success cannot be measured in numbers. 'Rs 100 crore might be the yardstick to measure the box office success, but it is the film’s impact on people, the appreciation and compliments that cannot be measured,' says the 39-year-old actor, who reportedly worked out six hours a day for 13 months to prepare for the role.
