As expected, Pixar/Disney's Toy Story still tops the North American box office for the 2nd straight week. Sony Pictures' Grown Ups continues Adam Sandler's near-perfect string of $40M weekend comedy openings for a strong second-place finish. And Twentieth Century Fox's Knight And Day brings up third place with better-than-expected estimates of $20M for the 3-day weekend and $27M for its 5-day cume.
