I saw this over at Stargazing. It's really interesting. The Forbes article is more extensive and there are links to the biographies of each character.
1. Scrooge McDuck Uncle Scrooge comics $44.1 billion
2. Carlisle Cullen Twilight $36.2 billion
3. Artemis Fowl II Artemis Fowl novels $13.5 billion
4. Richie Rich Richie Rich comics $9.7 billion
5. Jed Clampett The Beverly Hillbillies $9.5 billion
6. Tony Stark Iron Man $9.4 billion
7. Smaug The Hobbit $8.6 billion
8. Bruce Wayne Batman $7.0 billion
9. Mr. Monopoly Monopoly games $2.6 billion
10. Arthur Bach Arthur films $1.8 billion
11. Jo Bennett The Office $1.2 billion
12. C. Montgomery Burns The Simpsons $1.1 billion
13. Chuck Bass Gossip Girl $1.1 billion
14. Gordon Gekko Wall Street $1.1 billion
15. Jeffrey Lebowski The Big Lebowski $1.0 billion
I don't know how they figured out that Smaug had $8.6 billion or that Carlisle Cullen has more money than Bruce Wayne, but it's a fun list to explore. The "explanation" at the end of the article says:
"Net worth estimates are based on an analysis of the fictional character’s source material, and where possible, valued against known real-world commodity and share price movements. In the case of privately held fictional concerns, we seek to identify comparable fictional public companies. All figures are as of market close, April 1, 2011."
Final valuations are calculated with a grain of salt, and a willingness to break our own rules."
Hope you enjoy it as much as I have.
