I realize there’s nothing new under the sun–Tolkien himself borrowed from Norse mythology. At the same time, the more I review the Harry Potter books, the more I see the echoes of J.R.R. Below is what Harry Potter cribbed from Lord of the Rings.
Considering I`m only, like, part of the way through The Two Towers, these are just the ones I’ve found so far.
|Entity||Harry’s version||Frodo’s version|
|Devoted, lower-class sidekick||Samwise||Ron|
|Dangerous, grasping willow tree||Whomping willow||The one that Tom Bombadil rescues Pippin and Merry from|
|Long-haired and -bearded wizard mentor/protector whose apparent feebleness belies his wizardly power||Dumbledore||Gandalf|
|Evil being who was banished but not destroyed, who is slowly regaining power and regrouping his army and is often referred to as “he-who-must-not-be-named/whose-name-we-dare-not-speak”||Voldemort||Sauron|
|Permanent forehead scar||Harry’s||Merry’s|
|Troll unleashed by enemy||Mountain||Cave|
|Character who could be portrayed by Robbie Coltrane||Hagrid||Gimli|
For good measure, here’s some stuff ripped off from The Black Cauldron.
|Oddly cute creature almost annoying in his devotion to the protagonist, who refers to himself in the third person||Dobby||Gurgi|
|Animal assistant with name that sounds like “Henwig”||Hedwig||Henwen|
|John Hurt as||Mr. Ollivander||The Horned King|
