Chetan Bhagat's bestseller 'One Night @ The Call Centre' has been adapted into a film, HELLO.

Since the book was extremely well received all over, more specifically in certain pockets of India, like Bangalore, Delhi, Pune and Ahmedabad, HELLO director Atul Agnihotri and Chetan Bhagat have decided to tour these cities to promote the film.

"The book sales were tremendous at these places and we plan to kickstart the HELLO campaign by visiting these cities in the first round, " Atul Agnihotri informs me.

The director and writer along with the star cast of the film will visit Delhi on 25th and Bangalore on 27th September. Later, they plan to interact with the call centre employees at Pune and Hyderabad.
