Riythvika is an Indian film actress who appears in supporting roles in Tamil films. After starting her career with a role in Bala’s Paradesi (2013), she made a breakthrough with her performance as a feisty housewife in Pa. Ranjith’s Madras (2014). In 2018, she won the Tamil reality television show, Bigg Boss Tamil
Riythvika studied at Justice Basheer Ahmed Sayeed College For Women (SIET) in Teynampet, Chennai. She has stated that she had always dreamt of acting in films and that she used to act out scenes and reel out dialogues from films as a child. While studying at SIET, she acted in a number of short films and sent her photos to film PROs, trying for an entry into the cinema industry.
During that period, director Bala was casting for his next project, Paradesi (2013), an adaptation of the English novel Red Tea (1969), which delves into the plight of tea plantation workers in the Madras Presidency during the British Raj. After going through a couple of auditions, she was selected to play the role of Karuthakanni, a young woman who gets tortured and sexually exploited in the plantations. She went on to act in Vikraman’s romance film Ninaithathu Yaaro (2014) before being chosen by Pa. Ranjith for Madras (2014) to play a pivotal supporting role opposite Kalaiyarasan. Her portrayal of a North Chennai girl was lauded by critics and she won the Filmfare Award for Best Supporting Actress – Tamil besides several other nominations.
The success of Madras prompted Ranjith and other film-makers to often cast her as a girl from a lower socio-economic background. In this trend, she notably appeared as a drug addict in Kabali (2016), and as a prostitute in Iru Mugan (2016),Torchlight (2018) and Sigai (2019). In other assignments during the period, she featured as a liberal radio jockey in Oru Naal Koothu (2016), and as a ghost in the horror comedy, Onaaigal Jakkiradhai (2018).
She is currently working on projects including Odavum Mudiyathu Oliyavum Mudiyathu, and an untitled biopic of actor-politician MGR, where she essays the role of Janaki Ramachandran. For the latter role, Riythvika carefully studied the habits and behaviour of Janaki, including by watching her old films. In 2018, she won the second season of the Tamil reality television show Bigg Boss.
