Mumbai, Oct 29 (IANS) Filmmaker Rituparno Ghosh wears many hats. From director to costume designer to art director or even editing a widely read Bengali magazine. But in Deepa Mehta's and Amitabh Bachchan-starrer period film "Exculsion", he turns a lyricist.The Toronto-based Mehta has asked her prolific colleague from Kolkata to write a song, and that too in the Braj Bhasha.

"I think Rituparno is a wonderful human being and an astonishing filmmaker. But when I heard his songs in the Braj Bhasha sung by Shubha Mudgal for Raincoat, I knew I had found my lyricist for 'Kamagata Maru'," Mehta told IANS.

"The song will be filmed on a nostalgia-driven Bihari travelling far away from home."

And Ghosh has agreed to do it.

"Deepa is someone whom I really respect. And why just her? I've also written Bengali dialogues for Mira Nair's The Namesake and for a number of Aprana Sen's films including 'Yugant' and her documentary 'An Unordinary City' on Kolkata," Ghosh said.
