If this weekend's box office results say anything, it's that success in the movie business resists predictability. How else do you explain the money that Time Warner's (NYSE: TWX) The Hangover is grossing? I haven't seen the film, so I'm sure there's something to it. Nevertheless, it just didn't seem like it would be a big hit. Guess the word of mouth on it has been pretty good.

Hangover, as of early estimates at Boxofficemojo, took in $33 million at domestic theaters over the past three days, good for first place. It beat Disney's (NYSE: DIS) Pixar project Up, which took in about $30 million and came in second. Hangover actually was the number-one movie last weekend as well. So far, it's taken in more than $100 million.

Disney (NYSE: DIS) and Pixar have a great thing going with their new cartoon Up. Last weekend, the movie debuted in the top spot. This past weekend, Disney just might retain that number-one designation. And if it does, I can tell you that this is cool news.

It's very close. As of this writing, early estimates at Boxofficemojo credit Up with a take of $44 million for the past three days at domestic theaters. Time Warner's (NYSE: TWX) The Hangover is said to have grossed $43 million. If those numbers by any chance hold, then Up will be in first place and Hangover will come in second.
