Do you mean the mountain transformers? Sorry, they weren't.
Here's a quote from the "thunder-battle" scene:
> He knew that something unexpected might happen, and he hardly dared to hope that they would pass without fearful adventure over those great tall mountains with lonely peaks and valleys where no king ruled. They did not. All was well, until one day they met a thunderstorm, more than a thunderstorm, a thunder-battle. You know how terrific a really big thunderstorm can be down in the land and in a river valley; especially at times when two great thunderstorms meet and clash. More terrible still are thunder and lightning in the mountains at night, when storms come up from East and West and make war. The lightning splinters on the peaks, and rocks shiver, and great crashes split the air and go rolling and tumbling into every cave and hollow; and the darkness is filled with overwhelming noise and sudden light.
To me, that quite clearly is a symbolic "battle." Not mountains turning to golems or giants or transformers or what-not.
I think Tolkien meant the giants to be real in the Hobbit. The paragraph after then one you quoted starts with:
When [Bilbo] peeped out in the lightning flashes, he saw that across the valley the stone-giants were out, and were hurling rocks at one another for a game, and catching then, and tossing them down into the darkness where they smashed among the trees far below, or splintered into little bits with a bang...They could hear the giants guffawing and shouting all over the mountansides.
"This won't do at all!" said Thorin, "If we don't get blown off or drowned, or struck by lightning, we shall be picked up by some giant and kicked sky-high for a football."
After the party escapes the goblins and gets through the mountains, Gandalf suggests blocking up the entrance in the pass through which they had been ambushed:
"I must see if I can't find a more or less decent giant to block it up again," said Gandalf, "or soon there will be no getting over the mountains at all."
You shouldn't, at least not completely. The giants in the book are giants--very large humanoids. They are not mountains that transform into something else.
Tolkien never actually describes them, so we don't know if they're stone-giants because they live among the stones of the mountains, because they throw stones, or because they are made of stone. I actually pictured them as Pdonis describes them, as very large humanoids, although I can't be sure.
But I don't think we can definitively settle the question of the giants' form, as we simply don't have enough data. So I suggest we branch out to another unanswerable question: would Gandalf have used Emacs or Vim? How about Sauron?
Tolkien doesn't come right out and say "giants are very large humanoids", but so what? They are described as throwing stones, which clearly implies that they are humanoids. The "very large" part is implied by the word "giant"; also, of course, there are plenty of mythological references to giants, in particular in Norse mythology, which Tolkien is known to have drawn upon, and they're always very large humanoids.
Yeah, most of the silliest things in The Hobbit movie [er... "Part 1"], where "silly" sometimes turns into "cringe-inducing", were places where they expanded a couple of sentences in the book into a long drawn-out super-CGI-heavy battle/chase scene.
I can forgive the moviemakers some poetic license, but these sequences typically feel very out of place, like very expensive padding, and detract from the general atmosphere rather than adding to it.
The worst, in my mind was the whole undergound goblin battle sequence ... realllllllllly long and repetitive, resembling a roller-coaster ride more than anything else. That sort of thing is great for Transformers Part VI, but it's utterly out of place in the Hobbit.
The book was not an action adventure, it was much more about exploration, leaving the familiar for the wider world, a sense of wonder, whimsy, etc, and the movie often just completely flubs this.
I really, realllly, wish stupid movie politics hadn't resulted in Guillermo del Toro quitting, because I think he could have done a much better job at capturing the atmosphere of the book. Pan's Labyrinth is a much, much, better movie, and shows a deft touch with this sort of material that Jackson (though I respect him greatly) just doesn't seem to have. Nature, for instance, in Jackson's movies is basically a very pretty backdrop; in Pan's Labyrinth, on the other hand, it's a presence, fantastic, a little threatening, full of portent and vast depths. That's the sort of sense The Hobbit should have had.
Wrong quote. The giants were in the book. Some quotes:
> When he peeped out in the lightning-flashes, he saw that across the valley the stone-giants were out and were hurling rocks at one another for a game, and catching them, and tossing them down into the darkness where they smashed among the trees far below, or splintered into little bits with a bang.
> They could hear the giants guffawing and shouting all over the mountainsides.
> "If we don't get blown off or drowned, or struck by lightning, we shall be picked up by some giant and kicked sky-high for a football."
