When will opens the diary to draw the clock face for Hannibal, its has ruled pages. But in the next close-up shot, he draws on a blank plain page.
When drawing the clockface for Hannibal, Will displays what the neurologist calls "spatial neglect," more commonly known as "left neglect." This can occur when the right hemisphere of the brain is damaged - the individual does not perceive items in the left field of vision and it is not due to lack of sensation. However, Will can perceive the left side of a clock or a watch, as is shown when he looks at his watch and tells the time. It would be an exceedingly rare occurrence for left neglect to be confined to expressive domains (as in Will's drawing the clockface) and not affect receptive ones, as well. This would be particularly true if, as the neurologist stated, the encephalitis encompassed nearly all of the right cerebral hemisphere.
At the dinner with the neurologist, they refer to ham as 'Iberico' as if it was a brand. The neurologist says: 'So we know how Ibérico gets his pigs'. In fact, Iberico is not a brand, it means Iberian, a special race, raised in freedom and, the most expensive, fed with acorns. Even Hannibal, a gourmet, doesn't seem to know what they are. And Iberico ham is never eaten with knife and fork.
When Lechter tells Will to draw a clock face in the journal and point the hands to represent the current time, Will calls out 7:16, which you can see on the watch he is wearing on his left wrist, but draws the clock at 7:13.
