Read the bit in director Satyajit Ray's book where he mentioned that he had difficulty shooting a scene where a small boy went looking for his sister in a field of tall grass. The boy just had to walk a few steps, look around, and walk on again. Satyajit Ray thought that it would be simpler to film a charging calvalry instead, cos then all you needed was well, a cavalry that charged.

He wrote: "But if you are faced with a scene of a boy looking for his sister in a field of tall grass, you are faced with a particular state of mind that produces a special kind of walk, and a special kind of stopping and turning of the head. You also have to calculate the exact duration of the halt, the exaction duration of each turn of head, the exact moment of the resumption of the walk. Of course, all this is further complicated if you are dealing with someone who has never faced a camera before, and with whom it would be futile to discuss outer manifestations of inner feelings."

If only some other directors would pay more attention to details.
