Time Warner's (NYSE: TWX) The Dark Knight will not rest. According to Boxofficemojo, the superhero flick finished in first place yet again over the weekend. It grossed an estimated $26 million at domestic theaters. Sony's (NYSE: SNE) Pineapple Express put forth a valiant effort to beat the Bat, but it came up a little short. That film came in second with roughly $22 million for the three-day weekend. It debuted on Wednesday, and its total gross to date is around $40 million. Sony was smart in opening it early so that it might gain some positive word of mouth for the weekend. Any movie going up against Dark Knight needs whatever assist it can get. Seth Rogen and Judd Apatow are becoming quite the Hollywood kings of R-rated youth-targeted comedies, and Pineapple Express will only serve to further cement their dominion in Tinsel Town.

Coming in third was The Mummy: Tomb of the Dragon Emperor, distributed by General Electric's (NYSE: GE) Universal. The fantasy flick took in $16 million and its total tally stands at $70 million. An okay performance, but nothing special. The Sisterhood of the Traveling Pants 2 from Time Warner was in fourth place with a $10.7 million take. That wasn't too good for a film that I thought had a lot of buzz, but the budget on the project isn't too steep at under $30 million, so maybe this one will do all right. Sony's Step Brothers took hold of fifth position. Disney (NYSE: DIS) continues to do horribly with its bomb Swing Vote. It dropped to ninth place.

So Time Warner's studio division will have the success of The Dark Knight to look forward to in future quarters as the movie, which now has over $440 million to its credit, progresses through home video and other ancillary channels. Disney will not have anything to look forward to from Swing Vote. And here's something else for Time Warner: Star Wars: The Clone Wars opens August 15. Time Warner will bring the cartoon to the silver screen ahead of the animated TV series that is set to debut later on. I think Clone Wars will surprise everyone by doing better than expected. The merchandise from Hasbro (NYSE: HAS) is out in the marketplace now pushing George Lucas' new chapter in his famous franchise. May the Force be with the multiplex.

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.
