Abhishek Bachchan and Aishwarya Rai [Images] seem to have become an inseparable onscreen couple after marriage. After Guru and the upcoming Sarkar Raj, they will be seen together in Rajiv Menon's new film, Dhun. It will be produced by Eros Entertainment.

Dhun is a musical love story, and will feature eight songs.

"I want to bring out the essence of music and the unsaid emotions in this film. This film is especially for music lovers," said Menon, who has earlier directed films like the Kajol-Prabhu Deva starrer Sapnay and Mammootty-Ash-Tabu starrer Kandokondain Kandokondain.

Menon hopes that A R Rahman will score the music for his film.

But Menon refuses to talk about the film in detail. "I do not want to comment much about it because I am already facing trouble after revealing the title to a publication," he said.

When asked why he chose Ash and Abhishek, Menon replied, "After Guru, I narrated the script to Abhishek and he seemed interested. Ash also showed interest in the script, so I signed them up for Dhun. Whether stars are real life couples or not does not matter if they have the ability to fit into the character and pull it off well."

Menon worked with Ash and Abhishek in Guru, and claims that it is a pleasure being associated with them. "Both Ash and Abhishek are wonderful actors, and very committed," he said.

Before he turned to direction, Menon has worked in many of Mani Ratnam's movies, as a cinematographer. "Mani is a wonderful director. We have never had any creative differences. We always discuss scenes and situations before reaching the sets. We do not discuss anything on the sets but I still know how Mani wants the scene," he said.

But while he's all excited about his musical film, its the mythological and historical films that he hopes to direct some day.
