20th Century Fox's Night at the Museum, which, with a total gross of $250.6 million, currently remains just ahead of Spider-Man 3 ($250.4 million) as the biggest moneymaker of the year (it opened on Dec. 20, 2006), has turned out to be a huge hit on home video as well. The studio's home entertainment division reported Thursday that it remained the top-renting DVD for the third consecutive week, while slipping to fourth place in sales. Meanwhile, Universal's romantic comedy Because I Said So took over the top spot on the Nielsen VideoScan First Alert sales chart, as it grossed $42.7 million -- almost as much as the $50.6 million it took in during its entire theatrical release.
