Pallabi Chatterjee is foraying into script writing with a crime thriller movie 'Game Plan' where she also essays the lead. "I had often felt the need to make a film like the late 70's Bengali blockbuster Lalkuthi. But while I had worked with all major directors from Aparna Sen to Anjan Dutt, that was someone else's project. In their films as an actor I had been asked to deliver but it was not my baby. So another Lalkuthi did not happen though I felt the need in the intervening period so long I could myself wear the director's hat," said the actress who feels the film has shaped up exactly the way she has envisaged. The actress is also producing the film.
