When Nadita enters the elevator (which is very small), Prithvi seems to suddenly appears and Nandita is shocked to see him. It is impossible for Nandita not to notice someone who is either already in the elevator or has entered elevator mid-journey.
In one scene Nandita and Prithvi's car is attacked by bulls and is rolled over in the ditch. But after few scenes the car is back in excellent condition.
After Nandita's car drives off in the rain the people from religious procession (who just passed by her car when a priest was talking to her) are not seen on the street any more.
After seeing Nandita in the shopping mall, Prithvi draws a painting of her. Later when Nandita is attacked by the spirit in the bathtub, the painting is shown again. Upon close inspection it can be noticed that those are similar but not the same paintings.
When Nandita is entering car, the glass is rolled up but when the shot is switched from inside the car, the glass is rolled down.
No one in their right mind will roll down window in heavy rain.
