If memory serves, and it probably isn't, Manhunter and Red dragon are pretty much the same movie, just one is a sorta remake.
Then there is Silence of the Lambs, and then Hannibal.
Manhunter and Red Dragon are pretty much the same movie - Hannibal Lecter, the early years.
Did you see Hannibal? I didn't want to see it after reading the book. I was also sorry I read the book. I didn't like at all what happened to Clarice.
