These are just estimates, but it appears “The Hangover” ($33,415,000) has repeated as box office champ, with “Up” ($30,515,000) coming in a strong second, in virtual spitting distance of the “surprise” R-rated comedy. John Travolta and Denzel came in third with “The Taking of Pelham 123” ($25,000,000), and the top five was rounded out by “Night at the Museum: Battle of the Smithsonian” ($9,600,000) and “Land of the Lost” ($9,153,000). Paramount Pictures must be thrilled their Eddie Murphy-headlined “Imagine That” got walloped by two movies that have been in release for more than two weeks, but then, really, did you expect anything less? I know I didn’t and that’s why my box office hot streak remains intact (that’s right, I don’t count last week as a loss).
