Career
Acting career
Moon Moon Sen started her career in films and television after marriage and motherhood. She made her debut in Andar Baahar. Her daring role in that film apparently created a storm of controversy. She had also starred in a suspense thriller100 Days with Madhuri Dixit. After Zakhmi Dil she did not appear in films until 2003 when she starred in an unsuccessful thriller Kucch To Hai. She could not match success of her mother. She'd acted in a Telugu movieSirivennela directed by the legendary Telugu director K.Vishwanath. Before and after entering the film industry, she appeared alone in some modelling assignments. She notably modelled for soap ads which were quite controversial in the 1980s. Apart from doing some television serials, she also did couple of Bengali tele-films. Sen said she would bare all even at 70.
"Age is not important, the attitude is. Sophia is the ultimate glam girl who can manage to look beautiful in such a picture even now. But yes, India too has beautiful women like Rekha and Hema Malini who can carry such a thing out with aplomb. In fact, I wouldn't mind myself if the shoot is done aesthetically and with taste."
Her film My Karma, directed by Korak Day earned her international praise, as the film received international awards and recognition for her as a "tough and sweet Indian wife, standing as a rock behind her husband". She is now doing a few films at a time. She is also apparently writing a cookbook in Bengali, which is yet to be published.
Moon Moon Sen married in 1978, to a descendant of the erstwhile royal family of Tripura state. They have two daughters, actresses Raima Sen and Riya Sen. She has high regard for her husband, for his consistent support of her professional acting career. Her late mother-in-law, Ila Devi, daughter of Indira Raje, was the princess of Cooch Behar, and elder sister of Gayatri Devi, the Maharani of Jaipur. Deeply religious, in spite of her bohemian screen image, Moon Moon Sen is committed to family life and grieved at her mother, Suchitra Sen's passing away on 17 January 2014, due to a heart attack. She immersed the ashes of her mother ritualistically in the Ganges, on Wednesday, 29 January 2014, the prayers attended by dignitaries, like West Bengal Chief Minister, Mamata Banerjee, close friends and family, who had missed the funeral, it being a hurried affair after five hours of death, as per the last wishes of the dying actress Suchitra Sen.
