In the scene where a surgeon is demonstrating the dissection of a cadaver and Munna tries to look over his shoulder there is a difference in position of actors in the frontal and side-on shots. Swamy who is seen immediately next to the surgeon on the surgeon's right in the frontal shot, is seen trying to pop his head over the crowd directly behind (and at some distance from) the surgeon in the side-on shot alternatively.
When Dr. Asthana barges angrily in the ward after the song "Seekh Lay", Zaheer, the patient hugs him to cool him down. During these shots Zaheer's head is alternatively towards the left or facing Dr. Asthana.
During the cadaver dissection scene, the professor notes that the outer layer of skin is the epidermis and asks what the inner layer of skin is, and one student enthusiastically responds, "Hypodermis!" and the professor nods to indicate that he is correct. The hypodermis is not a layer of skin at all; it is by definition that tissue that is underneath the skin. The two layers of skin are the epidermis and the *dermis*. (The prefix "hypo-" means "below," so the "hypodermis" is that layer of tissue that is "below the dermis.")
