Actor-turned politician Krishnam Raju is worried about cost escalation of his movie because of delay. After Baahubali success, Krishnam Raju roped in Radha Krishna Kumar to direct ‘Amour’ movie with his nephew Prabhas and Pooja Hegde in lead roles. About 30 per cent of the movie shooting was completed. Meanwhile, Prabhas became busy shooting for Saaho and did not give dates for ‘Amour’. The shooting for Amour started 2 years ago. Krishnam Raju has to shoot for ‘Amour’ fresh again because of changes in the face of Prabhas.
