We first meet the Hopkins version of Dr Lector in Silence with Clarice
This is of course the third film based on the first book, so is that version of Will going to see him in the cell
At this point Lector has been locked in the dungeon cell, away from the world and the sun, tormented for several years - if someone was not insane before anyone would be after that
This is the Hopkins version, what he calls a cross between a Tarantula and a Crocodile
With Mads in Hannibal we see him while he was still in society - this version is the sophisticated respected Doctor going round society who fits in and can disguise who he is
This version of Hannibal turns into the Hopkins version after many years in the cell
The Cox version is interesting as this was at the time only the first book was out and this was the first time Lector had been portrayed - as in the book there is this main intro scene and then there are a couple of others, Lector does not get much book or screen time
The Cox Lector appears normal, which is what people note a psychopath is like in real life, which is why you can't tell them apart from a normal person
