Seeman took up film direction as a career after being inspired by the films of
Bharathiraja and
Manivannan. He worked as an assistant director with Bharathiraja and Manivannan. Seeman started his career by directing
Panchalankurichi (1996), a village action film starring
Prabhu and
Madhubala. He collaborated with Prabhu again in
Iniyavale (1998), a romantic film which also featured actresses
Suvalakshmi,
Gouthami and
Keerthi Reddy. Seeman's third film was
Veeranadai (2000) with
Sathyaraj and
Khushbu, which garnered mixed review from critics and underperformed commercially. The failure of his initial films made it difficult for Seeman to attract producers to work on his next films. During the late 1990s and early 2000s, he worked on four other projects,
Vaigai Karai Oram with
Vijayakanth,
Anandham with
Karthik,
Karma Veerar with
Sarathkumar, and
Sethupathi Cheemaiyile with
Rajkiran, but all failed to develop beyond production. Seeman then made the village-based vigilante film,
Thambi (2006), starring Madhavan in the titular role. The film's production was briefly halted following a disagreement between the actor and director, after Seeman raised an objection to Madhavan returning to be with his family for the birth of his son. The film opened to mixed reviews but performed well commercially. His most recent directorial release,
Vaazhthugal (2008), received negative reviews and performed poorly at the box office. A reviewer from Sify noted the "execution is tacky and the final outcome is a dreary and boring message film that leaves you exhausted." The failure of
Vaazhthugal made it difficult for Seeman to find producers and actors to work on his other proposed projects, despite his interest in continuing work as a film director. In the late 2000s, Seeman attempted to make a film titled
Pagalavan with either
Ajith Kumar or Madhavan starring, but was unsuccessful. Seeman then hoped to make the film with
Vikram for director
Bala's production studio, but the venture did not materialise. In mid-2010, producer
Kalaipuli S. Dhanu agreed to finance the project, and Seeman held talks with
Vijay to be a part of the film. The actor later refused to work on the project, which prompted Seeman to speak out against Vijay. In 2013, Seeman approached
Jiiva,
Jayam Ravi,
Arya and
Vishal to work on the project, but none of the actors agreed to be a part of the film. In 2017, Seeman was in talks with
Vijay Antony to feature in the lead role, and then with
Silambarasan in 2018, but both actors later opted to prioritise other projects. In 2017, Seeman announced another project titled
Kobam with
G. V. Prakash Kumar in the lead role. However, despite an announcement, the film failed to find producers and was stalled. Since the mid-2000s, Seeman has mostly worked as an actor. His notable roles including supporting characters in
Pallikoodam (2007) and
Evano Oruvan (2007). == Politics and activism ==
