Why did Arwen go to find the hobbits?

[Morquesse]

Since that part was left out of the movie what made Arwen go out to look for them?

Aragorn!

[The Saucepan Man]

She was probably trying to escape that overbearing, domineering father of hers ...

[Voralphion]

Even if Elrond knew that the hobbits were coming despite not being told so, why would Arwen be sent. She was the daughter of Elrond, (the lady of Rivendell) so why would her safety be risked especially when the Nazgul were near when there would have been plenty of others better suited to finding them and going against the Nazgul, such as warriors like Glorfindel.

Yes but I guess Peter Jackson did sort of have to explain Arwen throughout the film to make sure that audiences unfamiliar with the book knew where she came from and why Aragorn won't love Eowyn.

[Legolas]

We presume that Arwen is looking for Frodo for the same reason that Glorfindel did. In the book, Glorfindel finds Frodo after he has been looking for 9 days - not the 2 that Arwen proclaims. He left on October 9 and found Frodo at dawn on October 18. That was (yet another) odd and pointless change.

'Hail, and well met at last!' said the Elf-lord to Frodo. 'I was sent from Rivendell to look for you. We feared that you were in danger upon the road.'
'Then Gandalf has reached Rivendell?' cried Frodo joyfully.
'No. He had not when I departed; but that was nine days ago,' answered Glorfindel. 'Elrond received news that troubled him. Some of my kindred, journeying in your land beyond the Baranduin, learned that things were amiss, and sent messages as swiftly as they could. They said that the Nine were abroad, and that you were astray bearing a great burden without guidance, for Gandalf had not returned. There are few even in Rivendell that can ride openly against the Nine; but such as there were, Elrond sent out north, west, and south. It was thought that you might turn far aside to avoid pursuit, and become lost in the Wilderness.

This is another example of people who know the book making a movie without carefully considering the fact that everything should flow logically, even for those who haven't read the book. Glorfindel set out because of word from Gildor's group that Frodo met in the forest. In the movie of course, Gildor was never seen, thus botching the whole situation. Most viewers likely presumed that Arwen was just wondering why Aragorn hadn't made it home in time for supper. After all, she had Shake 'n' Bake, and Bilbo helped.

Way to go, Petey.

[Encaitare]

Ack! Plot holes make my head hurt!

I never even thought about that before... nice move, PJ. Would it have killed ya to put in Gildor?

[Mithalwen]

You think Arwen being psychic is a plot hole? - what about Gandalf thinking he could get from Hobbiton to Isengard and Back to Bree in the same time as it would take Frodo and Sam to get from Hobbiton to Bree... I know they only have little legs but really...

Well, if (and this is a big if) Agent Elrond and Book Elrond are indeed the same person, this is not really a problem. After all, Elrond's sons were always going off on scavenger hunts, camping trips, and other larks. Movie Arwen is every bit as tough as her brothers, Nonexistent Movie Elladan and Nonexistent Movie Elrohir, and we know that she can hurl epithets across rivers with the best of them.
