Disney (NYSE: DIS) soared to the number-one spot this past weekend with its new Pixar project, Up. The computer cartoon grossed roughly $68 million at domestic theaters as of early estimates, according to Boxofficemojo.

Disney took a lot of thunder away from News Corp. (NYSE: NWS) and its Ben Stiller comedy/fantasy Night at the Museum: Battle of the Smithsonian. That movie dropped to second place, taking in about $25 million.

Yesterday, I wrote about my nervousness over Marvel's (NYSE: MVL) The Incredible Hulk. Today, I'd like to talk about how I wouldn't be so nervous if the Iron Man sequel ended up being directed by someone other than Jon Favreau. There are two excellent articles on The Motley Fool discussing this issue, one by Nathan Alderman and one by Marvel expert Tim Beyers. At the time those articles were published earlier in the week, it had seemed that Marvel was reticent about ponying up a higher compensation package for Mr. Favreau on the heels of the awesome success of the first movie starring Robert Downey, Jr. David Maisel, chairman of Marvel Studios, apparently wants to be very conservative about the company's above-the-line costs. Alderman thinks Marvel should give Favreau the requested raise, while Beyers understands the Hollywood dynamics going on and can see why both sides are doing what they are doing.

By the time my own piece is published, it's possible Favreau may be confirmed as the director of the second Iron Man (as I write this, there are rumors that a deal has been offered). Regardless of what happens, I'd like to offer my opinion on whether or not Favreau is an absolutely necessary component for an Iron Man sequel.

He isn't. And if shareholders think he is, then they had better rethink their investment in Marvel. What shareholders must ask themselves is this: Is it the director that is responsible for the ultimate success of a Marvel film, or is it Marvel management and the intangible value of the Marvel intellectual-property portfolio? Which element adds more equity? As far as I'm concerned as a shareholder, I'm investing in Marvel. I'm not investing in Jon Favreau. Any investor who believes that any one director is indispensable is going to be in for a stomach-churning ride, because when the day comes that a Jon Favreau or a Sam Raimi (he directed the Spider-Man flicks) decides that Marvel is no longer paying them what they're worth and jumps ship, the stock could easily see an overreaction sell-off.

Despite lukewarm reviews and a smattering of sub-plots spilling over in a bloated script (in this fan's opinion), Spider-Man 3 ensnared millions of fans in its web over the weekend, setting box-office records and raking in $375 million in ticket sales around the globe. The third installment following the escapades of our friendly neighborhood arachnid, trumped the previous record holder, Star Wars: Episode III -- Revenge of the Sith, which banked $254 million in its opening weekend in 2005.

In North America, the Tobey Maguire/Kirsten Dunst vehicle took in $148 million since Friday, topping the domestic box-office record set by Pirates of the Caribbean: Dead Man's Chest last July. Additionally, Spider-Man 3 -- distributed by Columbia Pictures, a unit of Sony Corp. ADR (NYSE: SNE) -- set a single-day record on Friday, selling $59.3 million in tickets, inching above the earlier record, also set by Dead Man's Chest. The latest installment was no frugal feat, costing nearly $260 million to produce.
