I remember that in the early 2000s, there were a few significant Bengali movies directed by noted directors. Kamaleshwar Mukherjee comes to mind as a director from that era. If "Teesta" is one of his works, that might be a point to include. But I'm not 100% sure. Let me verify the release year and director. Wait, some sources mention 2004 as the release year with Kamaleshwar Mukherjee directing it. The user said 2005, maybe different regions had different releases?
