Mumbai, Aug 3 (IANS): Director Rakeysh Omprakash Mehra couldn't have been happier with the "rare" acceptance that his latest offering "Bhaag Milkha Bhaag" has received from audiences of all age groups and strata.

"It's across the sections. From an 8-year-old to an 80-year-old... and in families, daughters and sons are taking their father (parents) and grandparents to see the film. This is rare! This was definitely not planned," Mehra said here Friday at the launch of a mobile game based on the film.

The film is a biopic on the life of former athlete Milkha Singh, and the film's success was given "because of such an inspiring life of Milkha Singh", said Mehra, adding: "That's a very special feeling."

"Bhaag Milkha Bhaag" is set to cross the Rs.100 crore mark, but Mehra says his priority lies in audience acceptance.

"When your work goes out to the masses and it's a commercial success, definitely it makes you feel very good and that means all your efforts are going out to more people," Mehra said.

"But more than just the commercial milestones, what is making us happy is the overwhelming response from people," he added.

The film has already become the third highest grosser of 2013. Actor Farhan Akhtar essays the role of former athlete Milkha Singh in the film.
