Throughout the late 90s and 2000s, Purnima became the face of mainstream Dhallywood. Her collaboration with late superstar and later with Riaz produced some of the most iconic romantic and social dramas in the country's history. Films like Moner Majhe Tumi (2003)—one of the highest-grossing Bangladeshi films—solidified her status as the queen of hearts. Her ability to balance commercial appeal with critical acclaim culminated in a National Film Award for Best Actress for her role in Ora Amake Bhalo Hote Dilo Na (2010). Transitioning to Popular Media and Television
Purnima won the Bangladesh National Film Award for Best Actress in 2010 for her performance in Ora Amake Valo Hote Dilo Na .
Perhaps the most impressive aspect of Purnima’s career is her ability to adapt. As digital media began to reshape entertainment consumption in Bangladesh, the industry shifted towards more realistic, story-driven films (the "New Wave" of Bangladeshi cinema). While many actors of the previous era faded away, Purnima reinvented herself.
