Kunchacko Boban is the grandson of film producer Kunchacko of the erstwhile Udaya Studios and the grandnephew of producer Maliampurackal Appachan. He started his career with the commercially successful film Aniathipravu produced by Appachan and directed by Fazil (though his debut was as a child artist in one of Fazil’s films from the early 80s). His roles in Nakshathrathaarattu (1998), Mayilpeelikkavu (1998), and Niram (1999) made him one of the popular lead actors of the late 1990s.

He became an instant teenage heartthrob following his first film, the Fazil-directed Aniyathi Pravu (1997). Kunchacko Boban and Shalini gained a reputation as a star pair; they went on to work together in four films. He stood out among the heroes of the late 1990s, when the middle-aged super stars concentrated on action films. Following the success of Aniyathi Pravu, Kunchacko Boban was cast in movies like Nakshathra Tharattu and Mayilppeelikkavu. In Nakshathra Tharattu, he was again cast opposite Shalini. Both films were fairly successful. Then he played a cameo in Fazil’s Harikrishnans, which marked the reunion of Mohanlal and Mammootty after 9 years. Then came a streak of flops like Chandamama, Ingane Oru Nila Pakshi, Prem Poojari, Sahayathrikakku Snehapoorvam, etc. He had a single success in 1998, Kamal’s Niram, which featured him opposite Shalini for the final time. Dosth did fairly well, but in an age when Dileep had the Midas touch, Kunchako’s performance was half-charged. Then he played a good comedy role in Sathyan Anthikkadu’s Narendran Makan Jayakanthan Vaka.

In 2005 he got married to Priya Ann Samuel and started concentrating on real estate business and was quite successful. In 2006 and 2007, he did not act much. He returned to films in 2008 with Shafi’s LollyPop, which also starred Jayasurya and Bhavana. In 2009 he again paired up with Jayasurya in Gulumal: The Escape.
After Gulumal: The Escape, he acted in Mummy & Me and in Sakudumbam Shyamala. Then he was cast in Lal Jose’s Elsamma Enna Aankutty, in which he had an image makeover with the character Palunni. After Elsamma he appeared in Shaji Azeez’s Oridathoru Postman and Saji Surendran’s Four Friends. His first release in 2011, Traffic is a Superhit. His later releases Seniors, Three Kings, Sevens and Doctor Love also did extremely well at the box office. By his astonishing personality, he is known as the ‘Gentleman’ of Malayalam Film Industry.
