Dr. Seuss' Horton Hears a Who proved to have the biggest box office opening of not only this weekend, but of 2008 thus far. The Fox animated adaptation of the 1954 Suess classic roped in a healthy $45 million, high above industry expectations. The film, voiced by Jim Carey and Steve Carell, is the fifth biggest grosser in animated, G rated history. This can mean only one thing: A full-length theatrical adaptation of Green Eggs and Ham isn't very far off in the future.

Last week's 10,000 B.C. came limping into second place with a paltry $16.4 million, though it made double that of its third place competitor Never Back Down. The high-kicking kiddy Fight Club only managed to scrap $8 million worth of ticket sales together, but that was enough to make it a modest hit for Summit releasing. We will most likely see a sequel to this Karate Kid wannabe sometime in the near future.

Doomsday, the week's only other major release, hit with a thud in seventh place earning an estimated $4.7 million. On the indie front, Funny Games took in $520,000 on 289 screens, while the drama Sleepwalking raked in just under $50,000 on 30 screens.

Next week, Horton and the Mayor of Who-Ville will have to face down the behemoth Tyler Perry's Meet the Browns as well as Shutter, Drillbit Taylor, and The Grand.
