In addition to my early comment, i would also like to point something out. Now, ive never relised it before but in FOTR when Sam goes after Frodo and drowns, and we see the hand shot in the water, it is the same but reversed in ROTK when Frodo is hanging off the Cracks of Doom!
I think this is a very beautiful and excellent thing that PJ has done to show the friendship and couarge between the to <----even if some of us are a little slow at picking it up!
Has anyone else noticed this?
