In 2009, Sen announced her next Bengali film "Iti Mrinalini", which starred Konkona Sen Sharma, Aparna Sen, Rajat Kapoor, Kaushik Sen, and Priyanshu Chatterjee. First-time screenwriter Ranjan Ghosh co-authored "Iti Mrinalini". This was the first time that Sen collaborated with any film writer or became attached to the curriculum of a film institute. The screenplay of "Iti Mrinalini" was an assignment in the Screenwriting syllabus at the Mumbai-based film school Whistling Woods International. It was also a major first in Indian screenwriting, as the first time that any screenplay from an Indian film institute was actually filmed. The film was released on 29 July 2011.
