Bilbo Baggins (played by Martin Freeman), of Bag End, probably shouldn't have been quite so eager to join Gandalf for his unexpected journey — but, sometimes, when the road calls you have to answer. (The same recklessness would later take root in Bilbo's nephew, Frodo.) Besides, good burglars are hard to find.
Brother of Dwalin, Balin (played by Ken Stott) would survive the events of The Hobbit and breathe life into the Mines of Moria ... only to be killed by orcs. When Frodo Baggins and the Fellowship of the Ring attempts to travel through the Mines, they find Balin's grave: "Here lies Balin, son of Fundin, Lord of Moria."
Cousin of Bombur and Bofur, Bifur (played by William Kircher) seems to have survived a close encounter — and come away with a permanent souvenir.
Bombur's brother and Bifur's cousin — yes, dwarven family trees seem to have a lot of branches — Bofur (played by James Nesbitt) is rather fond of the clarinet.
Ah, Bombur (played by Stephen Hunter): His girth is matched only by his clumsiness. Legend has it that, in his old age, he gained so much weight that he couldn't get out of his own bed...unless hoisted out by a troupe of young dwarves.
Now here's a dwarf you don't want to meet in a dark alley: If Middle-earth had biker bars, you'd probably find Dwalin (played by Graham McTavish), brother of Balin, in one.
The only dwarf to get a last name — so you know he's important — Thorin (played by Richard Armitage) is the leader of the expedition into the wild to kill Smaug, in hopes of claiming his rightful place as King Under the Mountain.
Dori (played by Mark Hadlow) can count Ori and Nori as his brothers. Rhyming, it seems, was a mandatory convention when it came to naming dwarf siblings.
If Abercrombie & Fitch had a Middle-earth location, Fili (played by Dean O'Gorman) and his brother Kili would be the dwarf-outlet poster boys.
Just look at him: Kili (played by Aidan Turner) is totally rocking the Blue Steel.
Gloin (played by Peter Hambleton), son of Groin — no, really — is both the brother of Oin and the father of Lord of the Rings' Gimli. It seems that escorting Hobbits about was the family business.
Little is known about Nori (played by Jed Brophy), brother of Ori and Dori, save his apparent predilection for stylish coiffure.
If you've been paying attention, we're sure you know who Ori (played by Adam Brown) is related to. (Okay, fine, his brothers are Nori and Dori.) And just by looking at him, you can tell he's the sharpest tool in the shed.
Another son of Groin — that is never going to get old — Oin (played by John Callen) joined his brother Gloin on Thorin Oakenshield's quest to kill the dragon Smaug and roll around in gold coins like a stripper in singles.
Gandalf the Grey
Since The Hobbit takes place before this wizard (played by Ian McKellen) fell at the hands of a Balrog in The Fellowship of the Ring (and was then — DECADES OLD SPOILER ALERT — reincarnated as Gandalf the White), we get the shaggy trickster we so fondly remember.
