In the beginning of the extended version of The Two Towers, when Sam and Frodo first meet Smeagol, just after Smeagol throws Frodo to the ground and jumps on the wall, to go back again, Sam steps up and grabs Smeagol by the waist. Just after Smeagol bites Sam in the neck...look at Sam's right hand...IT'S NOT THERE!!! It has disappeared into the CGI version of Smeagol..But I still love the movie!!!:)
