He started his career as a clap boy for the film
Kasturi Nivasa. Both films alongside
Anand became successful and earned Shivrajkumar the tag of "Hat Trick Hero". Rajasekhar again directed him in films during 1980s like
Ade Raaga Ade Haadu and Aasegobba Meesegobba with former being average grosser and latter being a super hit. He introduced Rajkumar's second son in the leading role in family comedy
Nanjundi Kalyana which also marked the debut of actress Malashree. The film became a successful venture which led the cast and crew to collaborate with
Gajapathi Garvabhanga in a similar genre.
Hrudaya Haadithu and
Mannina Doni were both films which starred Ambareesh and were adapted from novels which were successful. Both films featured Ambareesh in a soft natured character as opposed to action roles which he was playing up to that part of career.
Midida Shruti and
Muthanna which he again directed with Shivaraj did well. After the average success of
Mana midiyuthu, Rajasekhar after four years sabbatical returned with
Hrudaya Hrudaya, a romantic film with Shivarajkumar and Ramesh Aravind which was an average grosser but was well known for the song "O Premada". However, in the later part of Rajasekhar's career in 2000s, he directed mostly remakes with
Yaarige Saluthe Sambala and
Dakota Express being only successful ventures while his subsequent ventures like
Vijayasimha,
Pakkadmane Hudugi and
Ravi Shastri became failures.
Ravi Shastri was the last film he had directed before his retirement. ==Death==
