After receiving acclaim for his role of a serial killer in Kahaani, Saswata Chatterjee again plays the killer in 89, only this time his character is more complex and sinister. “I did not have to think much doing Bob Biswas in Kahaani. Here in 89, he is far more dark and you can’t read his mind,” Saswata told PTI.
To get into the skin of serial killer Sabyasachi, Saswata prepared himself psychologically over a period of time.
