Plagiarism? Or Simple Coincidence?

[Lord Halsar]

I'm not meaning to point fingers with this thread, and I'm not looking for trouble, but it has come to my attention of several occurrences in both literacy and other sources that catch my suspicions of plagiarism.
The first is a scenario in the Inheritance Trilogy by Christopher Paolini. A mortal man named Eragon (sound familiar, Aragorn?) becomes infatuated to an elf princess named Arya (coincidence thy name is Arwen). Urgals-Orcs? Kull(correct me if that is misspelled) and Trolls? I'm seeing some similarity(even though the plot of the story itself seems more like that of Star-Wars than LotR to me).
The next is in J.K. Rowling's Harry Potter (again, not trying to raise trouble, just making a point). Giant spiders living in a dark forest? the name Longbottom is self-explainatory I hope.
And the last, is in a massively popular online game that many have grown to know and thrive on. World of Warcraft. Lich-King who was once a mighty Lord of men? Witch-king who was once a king of men. both of which ruled a frozen kingdom in the north of their world. And the name Anduin of the great river is also the name of the king of men who rules from the last bastion of human power in WoW.
Are all of these thing mere coincidences, accidents of all sorts? Or were they intentionally written and sold with full knowledge of the similarities that were already existent in the works of our beloved J.R.R.T?
For a final time I say, I am not trying to raise anger in anyone. Just saying how I see it, and I am not trying to discredit the authors and game that I have mentioned. I also realize that ther could indeed be much more to this list, but this was all that I could remember on short notice. Perhaps others will contribute to it....

Now, I know Christopher Paolini officially stated that both LotR and Star Wars were ag reat source of inspiration for him and considering his age I don't wonder that a lot is simply Tolkien's thoughts in a different but still very similar form.
And I personally don't hold it against him, if I were to write a fantasy book right now I would probably do something like that.
This is however also why I don't read his books. I mean, they may well be nice, but simply the fact that it's just LotR in another form with basically the same themes (that old guy as a Gandalf-like figure showing the young hero the way and all that).

Now, JKR...I quite doubt it. Names can well be coincidences and even if she took Longbottom so what? That's practically nothing. And giant spiders have been there for longer, I can recall some myths evisting in Japan about some giant spiders.
It can well be she used the books as a source of inspiration but I really can't see that many parallels, except of course again the Ganfalf-Frodo-like relationship between Dumbledore and Harry.

WoW...no comment on that. As far as WoW lore stuff is concerned I'm not really interested and I don't wonder they used the name like that.
I simply find the game a bad joke considering how Elves and Dwarves and all that are depicted there.

Yes. these were my thoughts as well after I posted this thread. But now I can't seem to recall anything that can be added to this point. I seem to remember that I did have many more examples of this matter, but I sadly cannot remember them.

A number of parallels can be found between HP and LOTR. There's the similarity in names between Wormtail and Wormtongue who play similar roles of betrayal but are later spared from death. There's also what happens when the characters wear the locket horcrux, and it begins to affect them in ways similar to how the ring affects people.

As for Star Wars practically any fantasy can seem to be the origin of it. Lucas based all of the Star Wars charcters and the plot of the movies itself on mythological archetypes (He said so much) therefore all fantasy stories will seem to resonate with them since many of them draw from the same meta-legends. In fact I once read a great essay which drew parallels between Luke and Yoda's relationship in The Empire Strikes back and that between Miyamoto Yoshi-tsune and Sojobo the Tengu King in the classic Japanese legend Ushiwaka Maru .
as for Giant Spiders they too have a long an honorable history in fantasy, from the Japnese legend of the spider woan metioned earlier to the Lovecraft Mythos's Atlach-Nacha.

If you look at just about any fantasy these days you'll find things that could be said to have come from Tolkien. It's not plagiarism, it's accident, inevitability or in some cases, lack of imagination, that's all. As for Rowling using the name 'Longbottom', well that's a common British surname

You sure know your Japanese folklore don't you. I can't even read most of their names, let alone the legends themselves(and believe me, I've tried).
