Time Warner's (NYSE: TWX) The Dark Knight is in the fight of its life. According to Boxofficemojo, it has a slim lead over General Electric's (NYSE: GE) The Mummy: Tomb of the Dragon Emperor at the domestic box office. The Batman flick is estimated to have taken in roughly $43.8 million, while the Mummy movie has about $42.5 million to its credit right. That's just too close to call. There is one thing for certain, however. Knight will approach $500 million in total box-office grosses since its cume currently stands at a little under $400 million. Awesome, indeed, although I think the movie will start to exhaust itself before it can gets to $500 million. We'll see if I'm correct on that count.

Moving on, we see that Sony's (NYSE: SNE) Step Brothers, GE's Mamma Mia!, and Time Warner's Journey to the Center of the Earth came in third, fourth, and fifth, respectively, over the weekend. Disney (NYSE: DIS), unfortunately, suffered an utter embarrassment with its new film project Swing Vote, starring Kevin Costner. The movie came in sixth place and only managed about $6 million. I've got to say that I don't blame Disney on this one. Concept and timing seemed solid to me, and it had a decent enough advertising campaign. However, I didn't like the performance of Disney's studio operations in the latest quarter, so it is too bad that this film couldn't have swung one out of the park.

Time Warner is really doing great with Knight, but I'm sure it's frustrating for shareholders to know that one hit film won't necessarily rally the stock for this big media conglomerate. It should drive studio and licensing profits down the line, however, so investors will at least notice that. I must admit that I thought the Mummy sequel was going to bomb over the weekend. Didn't seem as exciting as the first two. But GE's Universal division scored and seems to be having a decent summer at the multiplex, releasing hits such as Wanted, Hellboy II: The Golden Army, and the aforementioned Mamma Mia! Will Mummy will see a big drop next weekend? I fear it might. For now, it remains Batman's nemesis.

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

Since last year's summer movie preview featured mostly sequels and adaptations, this year's preview has been expanded to include more than just potential "blockbusters." The following is a chronological list of not only the most hyped film fare of the summer, but other noteworthy smaller entries, and a short commentary on each.



5/2 - Iron Man, Viacom (NYSE: VIA)'s Paramount Pictures
The first of two big Marvel Entertainment (NYSE: MVL) adaptations of the summer, the Robert Downey Jr. led Iron Man has been getting a ton of hype and critical acclaim. This is the second year that a comic book adaptation has kicked off the summer, following last year's Spider-Man 3, which grossed over $150M over its opening weekend.

5/9 - Speed Racer, Time Warner (NYSE: TWX)'s Warner Bros.
Another big-budget adaptation of a generations-old cartoon. Last year's Transformers was, to my surprise, a huge success, so maybe Speed Racer, in the capable directing hands of the Wachowskis, can be as well.
