Karthik Raj

Born in Chennai, Tamil Nadu, Karthik Raj is the eldest of the two sons to his parents. His father belonged to a wealthy family in Pallathur village near Karaikudi, but had migrated to Chennai at a young age.^[1] His father had a 30-year career in the film industry, starting as a production manager under A. L. Srinivasan and later working as an assistant to MGR, ultimately rising to the role of an Executive producer.^[1] He was one of the reasons for Karthik's entry into the entertainment industry.

Although Karthik excelled in school,^[2] due to his lack of interest in studies, he discontinued his schooling in his 12th grade and enrolled himself in a Diploma of Visual Design.^[3] However, due to the change in his family's financial circumstances, he discontinued his tertiary studies and started working in the merchandising department within a garment production house and later as an Assistant Producer in their production office.^[1][4] Whilst looking for a better job, he was recommended by his old neighbour, script writer, S. Ramana Girivasan, to work as an artist coordinator in the show Athu Ithu Ethu on Vijay Television.^[5]

Karthik's acting debut came about by chance in his third year of working behind the scenes at Vijay Television; he was offered the role of Karthikeyan by script writer Ramana Girivasan in the Vijay TV series Kana Kaanum Kaalangal Kalooriyin Kadhai (K5).^[4] The success of the series saw him landing the role of Karthikeyan in the 2013 series, Office on Vijay Television, where he starred opposite Sruthi Raj.

In 2014, he participated in his first reality show competition, Jodi Number One Season 7 with Nancy Jennifer, but was eliminated midway.^[6]

Apart from his on-screen roles, Karthik has also rendered his voice for Vetri, his co-actor in Kana Kanum Kalangal Kallooriyin Kathai, in the short film Yaanum Neeyum released in 2015 for Naalaiya Iyakkunar Season 5.^[7]

Taking to the silver screen, he has acted as a lead actor in the movies 465 ^[8][9] and Naalu Peruku Nalladhun Edhuvum Thappilla.^[10] The release of these films did not garner much attention and had underperformed at the box office.

In 2017, Karthik essayed the lead role of Adhitya in Zee Tamil's daily soap Sembaruthi, alongside newcomer Shabana Shahjahan.^[11][12] The series became a runaway success, captivating audiences across Tamil Nadu and propelling Karthik to new heights of fame.^[13]

While filming Sembaruthi, Karthik simultaneously prepared for his miniseries, Mugilan, starring alongside Ramya Pandian, where he would portray the role of a gangster named Mugilan. This preparation, which included gaining weight and growing a longer beard - a change in appearance that drew criticism from the audience who were accustomed to his characterisation of 'Adhitya' - involved a demanding 34-day shoot conducted concurrently with his commitments to Sembaruthi. Mugilan was released as an OTT on the ZEE5 streaming platform on 30 October 2020 to mixed reviews.^[14] In December 2020, however, Karthik Raj was replaced in Sembaruthi "due to unforeseen reasons," as quoted in the channel's official statement.^[15][16]

In July 2021, Karthik established his own production company, K Studios and began works on his self-produced, partially crowdfunded film.^[17] The pre-production phase commenced in August 2021, with principal photography beginning in November of that year. Titled Black 'n' White in October 2022, the film featured Karthik alongside newcomer Arthika and Shravanya Srinivasan. It was released as a direct-to-television film through Zee Tamil in May 2023.^[18]

Following a two-year hiatus, Karthik resumed his television career in 2022, portraying Karthikeyan in the Zee Tamil serial, Karthikai Deepam, reuniting with his Black 'n' White co-star, Arthika.^[19] The first season of this series surpassed over 600 episodes,^[20] with the second season premiering in late 2024, featuring newcomer Vaishnavi Sadish as his on-screen pair.^[21][22]

At the age of 25, Karthik married his girlfriend, Yashi, a Muslim woman, in an interfaith registered marriage.^[23] However, they separated a few years later and their divorce proceedings were finalised between 2019 and 2020.
