Once again, Forbes magazine has taken a very realistic look at the bottom lines of fake people for its "Fictional 15." The list compares the wealth of fictional characters using an "analysis of the fictional character's source material, and where possible, valued against known real-world commodity and share price movements."

Just in time for "The Avengers," Iron Man's alter-ego Tony Stark made the list - coming in 5th, with an estimated net worth of $9.3 billion. This put Stark ahead of another superhero's alter-ego, the man behind Batman's mask, Bruce Wayne, who will also be seen onscreen when "The Dark Knight Rises" debuts this summer.

Topping the list this year is another topical upcoming movie character, Smaug, the red-gold dragon who will be seen in Peter Jackson's "The Hobbit" films. According to the number crunchers at Forbes, Smaug rests his armored belly on a bed made up of $62 billion worth of gold, priceless Elvish armor, and other baubles.
