Prabhu is an Indian film actor and producer who has predominantly appeared in Tamil language films. He is the son of veteran actor Sivaji Ganesan, while his own son Vikram Prabhu is also an upcoming Tamil actor. After making his debut in Sangili (1982), the actor has played a series of leading and supporting roles, earning the Best Actor award recognition by the Tamil Nadu state for his portrayal in Chinna Thambi (1992).
After leaving Bishop Cotton's school in Bangalore, Prabhu got involved in film production as an executive producer and worked alongside his uncle and mentor V. C. Shanmugam, who had insisted that Prabhu learnt the film making process through a disciplined way, giving him general tasks such as pulling up chairs for artistes. Prabhu's father, actor Sivaji Ganesan, had initially expressed reluctance in allow Prabhu to pursue an acting career but through his work in the industry, he began to receive offers from film makers to feature in their films. He subsequently made his acting debut in C. V. Rajendran's Sangili (1982), a remake of the Hindi film Kalicharan, where he was cast in a supporting role. By the time Sangili released, Prabhu was working on six films including Charuhasan's Pudhiya Sangamam and Gangai Amaren's romantic film Kozhi Koovuthu, which became his first commercially successful venture. After featuring in around thirty films, including nineteen with his father including Santhippu, Mirudhanga Chakravarthy and Neethibathi, Prabhu's career graph registered a drop and he began to reconsider the type of films he had signed. He opted against featuring in films co-starring his father and consciously began to choose subjects rather than accept as many offers as possible.
Among the first films he signed after taking the break included G. M. Kumar's Aruvadai Naal (1986) and Manivannan's Paalaivana Rojakkal alongside Sathyaraj, both proving successful. Subsequently the following period saw a series of commercial successes in 1988 for the actor notably S. P. Muthuraman's Guru Sishyan with Rajinikanth, Mani Ratnam's Agni Nakshatram with Karthik and P. Vasu's family drama En Thangachi Padichava. The success of the latter film prompted more successful collaborations in the same genre between Prabhu and Vasu with Chinna Thambi (1991) and Senthamizh Pattu (1992) also receiving a similar reception, with the actor earning the Best Actor award recognition by the Tamil Nadu state. He subsequently worked in his hundredth film R. V. Udayakumar's Rajakumaran, before portraying well received roles in K. Balachander's romantic film Duet (1994) and Priyadarshan's Malayalam period film Kaalapani (1996) alongside Mohanlal. Prabhu went through another barren spell in the late 1990s, when several films after the success of Panchalankurichi failed to do well, prompting another image change away from his village do-gooder roles. Moving away from action films, Prabhu selected scripts which would appeal to family audiences in the early 2000s and collaborated with film makers including Rama Narayanan and T. P. Gajendran, working in a series of minimum guarantee return films.
Prabhu then made another career change and began accepting film offers in which he would play a supporting rather than the leading role and featured alongside Kamal Haasan and then Rajinikanth in two big budget ventures, Vasool Raja MBBS (2004) and his home production Chandramukhi (2005). Since then he has gained acclaim portraying characters including a caring guardian in Unakkum Enakkum, Thaamirabharani and Ayan; while he has also been seen in detective roles in action films, notably Billa (2007) and then Kanthaswamy (2009). He has also played other acclaimed supporting roles in Mani Ratnam's Raavanan (2010) and Aishwarya Dhanush's 3 (2012), while he has ventured into playing similar roles in Telugu, Kannada and Malayalam films.
Prabhu was born to actor Sivaji Ganesan and Kamala. His elder brother Ramkumar is a film producer and he has two sisters Shanthi and Thenmozhi. He is married to Punitha and has two children Vikram Prabhu and Aishwarya Prabhu, with Vikram making his acting debut in the 2012 film Kumki. There were reports throughout his career linking him with actress Kushboo and in an interview, Kushboo confessed her being in a live-in relationship for four-and-a-half years, with actor Prabhu, they got married on September 12, 1993, and subsequently divorced.
