Koena is named after the renowned Bengali river. She studied Psychology at Kolkata, before coming to limelight, by winning Gladrgs Supermodel Contest in 2002. She took the modeling world by storm and later on went on to become the semi-finalist of Miss Intercontinental. Her modeling for the TV Commercials of ACP Whisky, Miranda, Maruti Alto and Clinic All Clear turned out to be a big success and established her as a leading model.
Koena Mitra wanted to become an actress from her childhood and to enter the glamorous field. In this direction, Koena Mitra moved from modeling to acting. To start with, she featured in some of the music videos like Stereo Nation's Ishq, Aaj ki Raat, Akh Teri, and Channo by Jassi.
Koena Mitra's first appearance in the Bollywood was in an item number song in Ram Gopal Verma's Road. The song " khullam khulla" became a craze and Koena got typecasted as an item girl. After the success of her item number in Road, Koena was flooded with offers to do raunchy numbers in Bollywood movies. Nevertheless she refused all those offers as she was waiting to mark her role as an actress.
Koena Mitra had to wait two years to get into acting in films through Sanjay Gupta's Musafir. Even though she played a small role of a dancer who gets killed. People noticed her as a newcomer in Musafir because all the rest of the casts in the multistarrer were already very well known. Her second film Insan did not contribute much to her career growth. However she got all the attention that she had craved for from Suparna Verma who directed Ek Khiladi Ek Haseena. Suparna Verma liked the new face in Musafir and made Koena as the heroine of his new film. In this movie she plays the focal role of a psychiatrist.
Pritish Nandi's Ek Khiladi Ek Haseena was Koena's first claim to fame. In this movie she played the lead role opposite Fardeen Khan. This role was initially slated to play by Bipasha Basu. However it turned out to be a stepping-stone for Koena. Ek Khiladi Ek Haseena was not a big hit. Even then Koena made an entry to Bollywood actress club. Koena's dramatics are not very much impressive. Even then, she is able to procure roles with her dancing style and her sexy image. Two of her last films, Apna Sapna Money Money and Heyy Baby did well in the box-office.
Koena Mitra has grown as an actress with every role. She matches her body language with the dialogue. She is ready to experiment with roles and ready to do any role. She is eager to act under big banners, as she believes that they market their films well. She has set her eyes on higher goals in acting and let us hopes that her life would take her to greater heights.
