To be produced by Karan's Dharma Productions, the film will be directed by d'Silva.
"It was he who said things about me. Yes, Anurag is writing the dialogues for a film to be directed by Renzel d'Silva, that extremely talented writer who scripted 'Rang De Basanti'. Renzel is directing an emotional thriller for my Dharma Productions," Karan told.
"It was Renzel's idea to get Anurag on board for the dialogues. It had nothing to do with my patch up with Anurag," added Karan who has just returned to Mumbai after a short New Year holiday in Goa.
"I took the opportunity in Goa of doing some more reading for my next directorial project which I want to call 'Khan'. The film requires extensive research."
