Trivia, insights & behind the scenes
I.V. Sasi was Malayalam cinema's provocateur king; Ina got slapped with an 'A' certificate and moral panic despite zero explicit content. The film argues repression causes more harm than early sexual awareness.
Master Raghu (Vinod) retired from acting entirely after this—some say the role's intensity burned him out at age 14.
