Amitabh Bachchan has turned music composer for the first time in his career for R Balki's upcoming film Chup: Revenge of the Artist which has Dulquer Salman playing the lead role.

Narrating the story behind the same, R Balki shared, “It all happened very impromptu. I had asked Amitji to see the movie (Chup). After seeing it, he called me over and he played me a tune on his piano and said that’s what the movie and the characters made him feel. He was very touched. I was ecstatic. I asked him if I could use the tune and he immediately gifted it to the movie. Today Chup is the first film that has got Amitji's official composition as the score for the credits.”

In the official statement, R Balki mentioned that Chup is special to him for more than one reason. "For me the biggest reason is it marks the official debut of Amitabh Bachchan as a music composer. Amitji saw Chup and played an instinctive original melody on his piano as he relived the film. It was his way of expressing his feelings for the film, paying tribute. This composition, his gift for the film, will be the end title track of Chup. I don’t think there can be an artist whose sensitivity can beat Bachchan’s and Chup has his touch," he said.

Touted to be a crime drama the Chup stars Dulquer Salmaan, Sunny Deol, Shreya Dhanwanthary and Pooja Bhatt in key roles. The film has been produced by the late stock investor Rakesh Jhunjhunwala, Anil Naidu, Dr. Jayantilal Gada (PEN Studios) and Gauri Shinde. The film will be released theatrically on September 23.
