Mumbai (Agencies): Filmmaker Rakeysh Omprakash Mehra would begin shooting of his next movie 'Bhag Milkha Bhag' based on the life and times of legendary athelete Milkha Singh in August-September this year.

"Milkha Singh's life story is extremely inspiring. I had read his autobiography and approached him with my wish to make a film on it. Prasoon Joshi has written the movie. We researched for two years about Milkha's life and his past during our interactions with him in Chandigarh. All incidents have been captured in dramatised version for the film," said Rakeysh.

As a young kid, Milkha saw his entire family hacked to death in front of his eyes during the rioting that occurred on the Pakistan side of Punjab. All he could see and remember was his dying father screaming to him …"bhaag bhaag Milkha bhaag" (run run Milkha run).

Responding to his father, he ran across to the Indian side of the border and became one of the greatest runners of the country.

Rakeysh said he was on the hunt for a new face or a relatively new face to play the character of Milkha Singh.

"I had given Prasoon three four subjects to write a movie and he decided that he wanted to do Milkha's story first," he informed adding that he will produce the film as well.

"Once a movie is out of my system, I can't make the same thing again...'Rang De Basanti' was a huge success. But, I cannot repeat the same story of youngsters out to change the world. If something remains, I try to exploit it again and again," he added.

"My stories are original and hence it takes time to create a story. I normally take two years to finish the story before getting down to actual shooting," said Rakeysh reflecting more on his way of working.

Speaking about his productions, Rakeysh informed that an untitled movie starring Amitabh Bachchan with a new girl on a father-daughter relationship will go on floors in May.

According to him, a director should have something to say, a unique point of view. The producer should keep the business of the film intact. He said a filmmaker has to deliver entertainment to people by making good films at competitive cost.
