Prosenjit Chatterjee (প্রসেনজিৎ চট্টোপাধ্যায়) (also Prosenjeet Chatterjee or Prosenjit Chattopadhyay Prosenjit Chôṭṭopaddhae; born 30 September 1962), professionally known as Proshenjit and Bumba Da, is an Indian film actor and producer who works in Bengali and Hindi cinema. His fans affectionately call him Bumba Da. In rural Bengal he is addressed as Poshenjit/Posenjit. His rural fan base led him to perform in many films which had rustic settings, films that intellectuals initially shied away from, despite his popularity. Since 2003 with Rituparno Ghosh's Chokher Bali (co-starring Aishwarya Rai) he has acted in numerous films that won critical acclaim. In 2007 he received the National Award Silver Lotus for his performance in Dosar. He had acted in over 279 films as of October 2009. He is the Chief Mentor at International Institute of Photography in Kolkata to guide young talents.
