The filmmaker Rakeysh Om Prakash Mehra has moved away from AR Rahman and has teamed up with the music director trio Shankar-Ehsaan-Loy for his forthcoming movie ‘Bhaag Milkha Bhaag’.

The director was keen to have AR Rahman on board for the movie but because of Rahman’s busy schedule he couldn’t accommodate the movie.

“Mehra was adamant on pulling off a hat trick with Rahman. He waited for months for Rahman to accommodate BMB into his schedule. And Rahman, to his credit, tried his best. It was especially important that Rahman do Milkha because of the composer's impressive record with bio-pics Netaji Subhas Chandra Bose, The Legend of Bhagat Singh, Mangal Pandey ... But his impossible schedules and constant travel into three continents left Rahman with little choice,” said a source to a daily.

It was the lead actor of the movie Farhan Akhtar, who has always prefered the music trio be his debut movie 'Dil Chahta Hai' or his latest movies 'Zindagi Na Milegi Dobara' and 'Don 2', suggested the music director trio to Mehra. And as Mehra too was keen on working with them he decided to go with Shankar, Ehsaan and Loy for the first time.

“I've been very keen to work with Shankar-Ehsaan-Loy for many years. We go back almost 20 years. Ehsaan had composed music for my first ad film. Loy and I know each other from my student days in Delhi. Shankar's first music score for an ad film was for me,” he said.

In fact the music directors have already composed 4 tracks for the movie.

“They've already composed four songs for ...Milkha. Shankar-Ehsaan-Loy are going to sweep all the awards and win a million hearts with this score,” he said.

The shooting of movie is scheduled to begin in mid of February. Sonam Kapoor plays the female lead in this biopic on Olympic hero Milkha Singh.
