Her filmography reflects a blend of commercial hits and critically acclaimed roles, including:

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 entered the media landscape at a time when the film industry was undergoing significant transitions. Discovered by director Zakir Hossain Raju, she made her debut in the film E Jibon Tomar Amar (2003). Unlike many actors who struggle to find their footing, Purnima’s "girl-next-door" appeal, combined with her expressive eyes and natural acting style, resonated instantly with audiences.

From an industry perspective, Purnima represents the archetype of the "commercial heroine." She understood the pulse of the mass audience—those who sought escapism, melodious music, and emotional family narratives. Her films often featured high-energy dance numbers and dramatic storylines that catered to the heartland of Bangladesh. This made her a darling of the masses, securing her position in the "A-list" category for years.

Looking ahead, the keyword “Bangladeshi Model Purnima” is evolving. As of late 2025, she has announced her debut as a director for a digital short film under the government’s Bangladesh Film Archive initiative.
