Did Kalki Koechlin and Rajat Kapoor waive off their acting fee for 'Mantra'?

Upholding content over monetary benefits, Kalki Koechlin and Rajat Kapoor have waived off their acting fee for Nicholas Kharkongor's upcoming film, Mantra. The rest of the cast, including Shiv Pandit, have also worked gratis. The actors came on board the project because they believed in the script, which puts the spotlight on liberalisation and its impact on the economy and society in the '90s.
