Raja Chinna Roja was the first Indian film to feature live action with animation. It was AVM Saravanan's wish to do this, without any budgetary constraints. He also wanted AVM to become the first Indian studio to do this. The idea of blending live action with animation was inspired by Who Framed Roger Rabbit (1988).^[4]
