It looks like Marmaduke was less competition for the kiddie dollars than we expected, as Shrek Forever After still handily defeated all comers, moving into a few more theaters and scaring up another $25 million in ticket sales. I guess kids are no longer impressed by animals who don't have jobs? After all, why see a movie about a plain old dog when you can see a movie about a cat sword-fighter, or guinea-pig secret agents, or a mouse chef? (This may be why they're spinning Puss in Boots off into his own movie.) Maybe they should have called it Marley & Me 2: Puppy-Size Me!, and had Owen Wilson magically transform into Marley-maduke at the beginning of the film. Then it might have made $36 million in its opening weekend, like Marley, rather than the $11 million it did. Well, you know what they say: hindsight is a golden retriever. Rimshot!
