During the 2000s, Chandrahasan took a more active role in the management of Raaj Kamal Films International. During the problems faced during the release of Vishwaroopam, Charuhasan had taken a pivotal role in mediating with the opposition. Prior to his death, Chandrahsan completed acting in the lead role of a film titled Appathava Aattaya Pottutanga by debutant director Stephen Rangaraj.

The film, which featured him alongside Sheela, the mother of actor Vikranth, remains unreleased.
