We all know it - it's (almost) always like that; when a book is taken to the big screen, rarely do they are loyal to the original work. One of the clearest examples is, of course, the Lord of the Rings and The Hobbit movies. Tolkien die-hard fans have always felt that the movies are far from being as rich a story as the books were. Nevertheless, the movies came out as amazing representations on the original works of Tolkien.
So without further ado, I present you: things that happened on the books, but not on the movies part II.
Tom Bombadil
A mysterious (and most likely very powerful) character that appeared only in the books, who lived east of the Shire. Frodo and his companions encountered Tom, who felt the presence of the ring, put it on but was not affected by its influence, thus showing how powerful his will was. He was said to be really ancient, even stating himself: "Eldest, that's what I am...Tom remembers the first raindrop and the first acorn...he knew the dark under the stars when it was fearless — before the Dark Lord came from Outside...".
He was probably a Maiar or even a Valar (some may even argue that he was Eru Iluvatar himself). He would have made a great character on the films.
The Hobbit - Death of Thorin and role of Beorn
In the movies, Thorin is killed by Azog (while killing Azog at the same time). But in the books, Azog died before the Battle of the Five Armies, being killed by Dáin (Thorin's cousin), whereas Thorin was fatally wounded during the war at the Lonely Mountain gates. Upon seeing this, Beorn charged into the fray and killed Bolg, Azog's son, an event that didn't happen in the movies.

Sam, Legolas and Gimly sail to the Undying Lands
At the end of The Return of the King, we can see Bilbo and Frodo sailing on a boat along with Elrond, Galadriel and Celeborn. However, on his writings Tolkien talks about the death of Aragorn, and the subsequent sailing of Sam, Gimli and Legolas to the Undying Lands. The Undying Lands was a continent where the Ainur lived, along with elves. Men were forbidden to go there, but the Ring Beares and some members of the Fellowship of the Ring were allowed to go. Nevertheless, being on the Undying Lands doesn't grant immortality, and thus it can be assumed that all the non-elves residents died of old age at some point.

War in the north - the siege of Dale and the Lonely Mountain
Whereas most of the War of the Ring battles against Sauron foces take place at the southern part of Middle-earth on the movies, there were also many decisive battles on the northen part of the Middle-earth. The most important one took place at the gates of the Lonely Mountain, where Dain's Ironfoot dwarves allied with men from Dale battled against the Easterlings of Rhûn. In the end, both King Dain and King Brand died, but after learning about the free peoples victory on the South, the Easterlings lost the battle.

Dagor Dagorath
Although not a part of The Hobbit or The Lord of the Rings books, it is truly an event worth of mention. The equivalent of the Ragnarök on Norse mythology or the Apocaypse on the Bible, the Dagor Dagorath will be the final battle of Arda (Earth). It is said that Morgoth (the master of Sauron) will break free from his prison in the void, and will summon all his servants for a final war against the free peoples, which will be aided by the Valar. Dwarves will be rised again, Ents will awake from the forests of Arda, elves will return from Valinor, the Great Eagles will descent along with the Valar and Maiar, to fight Morgoth's minions and servants, such as Sauron, Dragons, Balrogs, Werewolves, Vampires, Orcs and all evil creatures ever created by Morgoth.
