Kumari 21F is a 2015 Indian Telugu-language drama film directed by Palnati Surya Pratap, and written and co-produced by Sukumar with Vijay Bandreddi and Thomas Reddy under their banners Sukumar Writings and P. A. Motion Pictures. Devi Sri Prasad composed the film's music and R. Rathnavelu was its director of photography. Kumari 21F focuses on a romantic relationship between Siddhu, a chef and Kumari, a struggling model.The film was produced on a budget of ₹60—150 million. Sukumar took inspiration from his college days in Razole where a young woman went to a picnic with some young men; a major undertaking for a woman at that time, which earned her the undeserved label of a "loose" character. Raj Tarun and Hebah Patel were signed to play the roles of Siddhu and Kumari. Kumari 21F was released worldwide on 20 November 2015 in about 500 screens. It received critical acclaim; praise was directed towards the film's climax, performances, cinematography and music. Kumari 21F grossed ₹380 million and earned a distributor share of ₹180 million during its run. It was declared a commercial success based on the return on distributor's investment of ₹100 million and became the 12th highest grossing Telugu film of the year.
