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.

This post was part of AOL Money & Finance's Best & Worst of 2007 feature. Voting has now closed and readers have chosen Oprah Winfrey as the most overpaid celebrity of the year. Be sure to let us know in the comments if you are pleased with this result.

Oprah Winfrey returns to our Most Overpaid Celebrity category after having lost the title to Paris Hilton last year. For 2007 she is joined by overpaid celebrities Madonna, George Lopez, and Russell Crowe.

Winfrey, Madonna, and Lopez all made the Forbes Celebrity 100, a ranking of Hollywood players by pay, influence, and popularity. Winfrey, of course, comes in at number one, both in terms of pay and power. Madonna's earnings placed her at number nine on the list, while Lopez came in at number fifty-one.

Forbes estimates Winfrey's earnings at $260 million last year, and her net worth in the area of $1.5 billion, making her the nation's wealthiest African American. She'll be adding two new reality shows to her media empire, which already includes a blockbuster daytime talk show, satellite radio show, magazine, and Broadway musical, as well as stakes in hit shows by Dr. Phil McGraw and Rachael Ray. The school for girls she founded in South Africa has drawn much media attention this year, and she's recently endorsed Barack Obama's presidential campaign. Winfrey has been called the world's most powerful woman, the most influential woman in the world, one of the most influential persons of the 20th century, the world's first black woman billionaire, and the greatest pop culture icon of all time. Can any mortal person live up to all that hype?
