Bombadil’s inclusion in the books was only done by Tolkien at the behest of his kids, or grandkids, because they loved the character so much from previous bedtime stories. Bombadil’s character would have been a bit incongruent with the flow of the movie’s storyline, added a great deal of expense and, more importantly, added a great deal of time, to an already long, long movie for a tangent that really led nowhere.
Tom is an interesting fellow, for sure, but a smart move by Peter Jackson.
Tom is central to the meaning of the story. A forest being who loved nature and his wife’s big knockers.
Curious: How do you know that?
