20th Century Fox’s Dr. Seuss’ Horton Hears a Who put the box office in a sleeper hold this past weekend, pulling in $45 million in its first three days of release, over $11,300 per screen. Brace yourself, parents, for the eventual adaptation and release of the entire Seuss catalogue. In second place, 10,000 B.C. raked in another $16.7 million, proving the spending power of CGI sabre-toothed tiger enthusiasts and putting the movie’s two-week total at just under $62 million. Never Back Down opened third for the weekend, with $8.6 million. The week’s other wide opener, meanwhile, Doomsday, wasn’t fooling quite as many folks; not screened in advance for critics by Universal/Rogue, it slotted seventh for the same frame, grossing $4.9 million on just over 1,930 screens, for a $2,544/screen average.

Rounding out the weekend’s top 10 were College Road Trip, with $7.8 million (now $24.2 million total); Vantage Point, with $5.4 million (now $59.2 million total); The Bank Job, with $5.1 million (now $13.3 million total); Will Ferrell’s R-rated Semi-Pro, with $3 million (now $29.8 million total); inert bodice-ripper The Other Boleyn Girl, with $2.9 million (now $19.1 million total); and The Spiderwick Chronicles, with $2.3 million (now $65.3 million total). Opening in 274 theaters, meanwhile, writer-director Michael Haneke’s controversial Funny Games grossed just under $511,000, or $1,864 per site.
