There will be five superheroes competing for the attention of weekend moviegoers come Friday. There's Marvel Entertainment Inc. (NYSE: MVL)'s duo Iron Man and The Incredible Hulk, Sony Corporation (NYSE: SNE)'s Hancock, General Electric Corporation (NYSE: GE)'s Hellboy (distributed by GE's Universal), and Time Warner, Inc (NYSE: TWX)'s Dark Knight. So, who's going to be the ultimate crime fighter?

I'll tell you which one prevails: Time Warner and its new Batman film, The Dark Knight, has the weekend all locked up. This is set in stone. The Hulk and Iron Man are pretty much done, Hellboy isn't a powerful enough brand name, and Hancock didn't deliver the big numbers I thought it was capable of during its debut weekend (since then, however, the movie has held up well, I have to admit). But you can bet that Dark Knight hits $100 million this weekend. Can you feel the buzz surrounding this blockbuster in the wings? I can. Several reviews I've read were full of cinematic worship for this new entry in the franchise, with special praise reserved for the late Heath Ledger and his portrayal of the fiendish nightmare known as The Joker. There's a decent marketing campaign behind the project, including promotion of the availability of IMAX (NASDAQ: IMAX) screenings. If there ever seemed a movie fit for Imax, this is it. Yeah, Dark Knight can't lose, it can only win big.

Of course, what about Time Warner's stock? It could certainly use a superhero right now, as it has been hovering in recent times not above Gotham City (although that would probably be treacherous enough) but above 52-week-low City. I can't say that a big opening weekend definitely won't move the stock a little just due to the excitement factor, but I wouldn't buy the company ahead of the film (I also wouldn't gamble with IMAX either). Time Warner simply is too large to be affected significantly by one movie. If you consider Time Warner at all, it would be for fundamentals and valuation (I think the company is cheap here, although with this market, I'd rather get it cheaper). Enjoy the movie first, think about the stock later...

Disclosure: I own GE and Marvel; positions can change at any time.

Arnold may not be back, but that doesn't mean a franchise can't move forward on its own.

According to The Hollywood Reporter, Sony (NYSE: SNE) and Time Warner (NYSE: TWX) stand to see some nice revenue generation for their studio segments in 2009 via a new sequel in the Terminator franchise, to be called Terminator Salvation: The Future Begins. Sony will take international distribution chores, while Time Warner will handle the domestic side of things.

As a fan of the Terminator series, I can tell you that it will be great to see another entry. And it will also be exciting to see if the brand can be carried by someone else other than Arnold Schwarzenegger. In fact, Christian Bale is set to play John Connor, the future rebel who battles Skynet and its evil cyborg army.

Yesterday afternoon, the world was shocked to learn of the untimely passing of Heath Ledger. Remembered for roles as varied as Patrick Verona in the teen-comedy 10 Things I Hate About You and Ennis Del Mar in Brokeback Mountain (for which Ledger earned a Lead-Actor Oscar nomination), the 28-year old was a talented and beloved thespian who possibly struggled with staggering demons.

His final bow will be taken in the iconic role of Batman villain The Joker, in The Dark Knight. The movie, a production of Time Warner (NYSE: TWX)'s Warner Brothers, still carries a release date of June 18.

A Best Buy (NYSE: BBY) location in San Diego reportedly responded to this bulletin by seizing the marketing opportunities. A black-and-white sign, propped in front of a display of Ledger films such as Brokeback and Lords of Dogtown, asks shoppers to "Remember a great actor through his great performances." While it is a nice sentiment to honor Ledger at the prime of his career, VH1's Best Week Ever asks (and I have to agree with them) -- is this sort of tribute "too soon?"
