Hrithik looks the same even in the flashback portions shown 15 years ago.
NTR enters the ship in his entry without clothes, he has bombs which all get exploded and then suddenly he has a remote which he blasts the ship.
When Hrithik falls off the cliff on the train the car manages to stay off the train without falling despite the car loosing balance.
When NTR comes out of the car which overturned he has just few scratches.
The scene when NTR enters the racing track, can clearly make out he has been superimposed in the track.
The skin colors of the young kids don't match with the adult versions, also the young Raghu talks proper Hindi but NTR has a south accent.
