My dueling counterpart Anders Bylund wants you to believe that Marvel (NYSE:MVL) can continue to leverage its famous superhero characters into a perpetual money-printing machine. Nice theory, but let's look at the real value of one of the most successful movie franchises in history, Star Wars:

Release Year


Worldwide Gross


A New Hope



The Empire Strikes Back



Return of the Jedi


16-year Gap



The Phantom Menace



Attack of the Clones



Revenge of the Sith

If you take a look at those numbers, what should pop out immediately is that the original film of each "trilogy" performed the best overall. The key lesson from Star Wars is that a producer can only push a successful franchise so far before it exhausts its fan base. And yes, the revival numbers are great, but the 16-year gap can be quite painful for any investor waiting for that potential.

Even Disney (NYSE:DIS) realizes this problem. How often do you see commercials indicating that one or another of its classics is available only "for a limited time," after which it will be put back in its vault for several years? Disney's a smart company. It knows the risks of overexposing its characters -- namely, losing a once-strong franchise.

Looking at Marvel, I already see X-Men done with its third iteration, Spider-Man finished its third, and Hulk in the process of its second. Those are some pretty big names, and they probably won't have anywhere near the near-term future earning power as they had in the recent past. Throw in some heavy leverage to support the moviemaking business, and Marvel's risk/reward tradeoff no longer looks so sweet, once you peel back the covers.

You're not done with the Duel yet! Go back and read the other entries, sound off in CAPS, and then vote for the winner!
