Okay, that's what I figured.
Hubby's other big thing is the fact that the whole "Tom Bombadil" sequence of events (which I am not familiar with because I haven't gotten that far in the book) is totally omitted in the movie. A matter of length, I suppose? Or not necessary to the plot?
The decision to leave out Tom Bombadil (if I may answer your question) was a matter of length, according to Peter Jackson. They only had time for mostly essenstial events. Otherwise the movie would have been, like, five hours long.:)
