Factual error: Gollum's body wouldn't sink into the lava if he fell in it as shown in the movie. Rather his body would burst into flames, and turn to ash. Falling in lava isn't like falling into a lake. Lava is more than three times denser than water, which prevents a human shaped body from sinking in.

Continuity mistake: In the second half of the film, Frodo has a scar on his lower right cheek, close to his chin. Many times throughout the rest of the film the scar changes position and size on his right cheek. It also appears on his left cheek in flipped shots (most obviously on the slopes of Mount Doom when Sam is cradling his head). (02:31:05 - 02:34:00)
Trivia: At the end of the film, young Elanor Gamgee is played by none other than Sean Astin's own daughter in a cameo. Not only that, but Frodo Gamgee (the baby) is played by Maisie McLeod-Riera, the daughter of Sarah McLeod, who plays Sam's wife, Rosie.
Question: When Déagol finds the ring, Sméagol asks to have it. When Déagol asks why, Sméagol says because it's his birthday and that he wanted it. Was it really Sméagol's birthday or was he already so quickly drawn by the ring's power that he only claimed it was in hopes that Déagol would hand it over?
Answer: It probably wasn't his birthday on that exact day, that would be too much of a coincidence. But close is definitely possible, or at least closer than Deagol's. Both were immediately drawn by the ring, heavily enough that they fought over it and Smeagol becoming the ultimate winner. Both did everything to keep it.





Answer: In the book, it absolutely was his birthday.
