News Corp.'s (NYSE: NWS) Dr. Seuss' Horton Hears a Who! came in at number one over the weekend, according to early estimates at Boxofficemojo. The movie grossed about $45 million at domestic theaters. Even if that number changes a little, there's no chance that it will be knocked from the top spot, considering that Time Warner's (NYSE: TWX) caveman epic 10,000 B.C. is estimated to have grossed about $16 million, which was good for second position.

Seth Rogen, who is the new toast of Hollywood and who will probably try to weasel his way into a Tom-Hanks kind of career (i.e., steadily move away from goofy roles and get into some serious dramas), provided his voice to one of the characters, as did his "frat pack" buddies Steve Carell and Jonah Hill. Jim Carrey, of course, is the big name on the movie's credits, but believe it or not, I thought of Rogen first when thinking about this flick -- guess his brand equity is indeed on the rise. It's not a movie I'd necessarily see, but it had a pretty good marketing campaign behind it, so I can understand its success.

Mammoths and multiplexes go hand in hand, apparently, especially if said mammoths are of the CGI variety. According to Boxofficemojo, 10,000 B.C., Time Warner's (NYSE: TWX) prehistoric epic, pounded the rest of its competition like an angry caveman warrior clubbing a saber-toothed tiger (I didn't see the film, but I assume this happened at some point during the plot). The film is estimated to have taken in over $35 million (final numbers are due later today) at domestic theaters over the weekend. Disney (NYSE: DIS) couldn't even come close to Time Warner -- its family comedy, College Road Trip, right now stands at a gross of $14 million, which was at least good enough for second place. Erstwhile Disney Channel phenomenon Raven-Symone star in the flick, so at least there was a little bit of synergy in that respect -- Disney is nothing if not about synergy, as we all know.

Sony's (NYSE: SNE) Vantage Point came in third, and Time Warner's Semi-Pro, starring the hilarious Will Ferrell, came in fourth. Lions Gate's (NYSE: LGF) The Bank Job, which achieved fifth position, actually did pretty well, considering that its per-theater average of approximately $3500 was much higher than the per-theater average for the two films above it.
