which lord of the ring movie did they show gollum kill his best friend

Gollum's purpose in The Lord of the Rings had been to destroy the Ring, which he could never have done if Bilbo had killed him.The character of Gollum, as read in The Hobbit, matches up perfectly with the Gollum we know from The Lord of the Rings. Gollum's crimes could never have been redeemed, and his death was the only way he could have found peace from the Ring's torment- certainly not the case for Frodo. This would have meant that Frodo and Sam would have had to fight over the Ring until one of both of them fell into the fire. If Gollum had been killed all those years previous, he wouldn't have been there to wrestle the One Ring away from Frodo and fall to his death. The only way to destroy the Ring would be to fall in with it- which is precisely what Gollum did. This proved that there could never be anyone strong enough to willingly throw Sauron's great weapon into the flames from which it had been born. Frodo had been more resistant to the Ring than anyone who had borne it in history, but when he finally stood where it could be destroyed, he couldn't do it. The most significant thing that Gollum did was at the volcanic fires of Mount Doom in The Lord of the Rings: The Return of the King.

At first, Gollum effectively playing the guide to the Ring-bearer seemed to satisfy the vital role Gandalf had predicted for him, but by the end of The Lord of the Rings: The Return of the King, it was clear that his part was far darker. Still, Frodo and Sam ended up stronger than he had thought, and they survived. He hoped to lead them into the lair of Shelob, the ancient and dangerous spider, and to their deaths. Of course, Gollum didn't take the two hobbits to Mordor out of the goodness of his heart. If he hadn't been there, it's impossible to know how long Frodo and Sam would have wandered before they found their way- or if they would have at all. Gollum had been taken to Mordor and Mount Doom before, and his skulking allowed him to know the secrets of the dark country. So, it was ultimately good that Gollum was there to lead them. Frodo and Sam lost their guides and protectors at the end of Lord of the Rings: The Fellowship of the Ring, and the way was unclear and dangerous. Traveling across Middle-earth to a place they had never seen was no easy task.
