I saw all 3 of these movies and have them on DVD. I LOVE scary movies. Red Dragon is actually a pre-quel to Silence of the Lambs and was a remake of Manhunter, where the Hannibal Lector character was first introduced. For those of you who liked Red Dragon, I recommend checking out Manhunter. I think it's a better version and a little more scarier.
(Anthony Hopkins doesn't appear in this one, Hannibal is played by Brian Cox)
