The plot of the animated production is in most respects similar to that of the book, which was already styled as a classic children's novel.
So it's adapted in that vein for a younger audience but certain plot points are significantly compressed due to the time limitations of the format.
In addition, certain scenes are obviously edited for commercial breaks. In general, alterations include simple omission of additional detail, as the producers expressed their desire to adhere to the written text, including lyrics adapted from the songs in the book but in much longer and greater format.
When all the dwarves in the beginning just come out of nowhere, they come all at once.
In the book, Gandalf put a sign on the door for all the dwarves to come and Bilbo had to keep opening and closing the door.
Everything that happened in the cartoon has mostly happened in the three new movies.
I really enjoyed this. It's pretty funny watching it and comparing everything to how it all looks now. A lot sure has changed!
Here's what the dwarves look like now compared to their previously animated 1977 renditions.
So there you have it! Does this make you interested in going back and checking out the 70s cartoon epic?!

I would recommend watching this before you go see the battle of five armies.
