Unlike most Mike Tyson fights, The Hangover‘s win was no knockout.

After a back-and-forth battle with Up, Todd Phillips’ film about an eventful bachelor party edged out the animated pic by less than $1 million. Hangover - which features no major stars (unless you count the boxer) - grossed nearly $45 million on its opening weekend. That’s the third best debut for an R-rated comedy ever. (Only Sex and the City and American Pie 2 have done better.)

Meanwhile, a project actually featuring an A-lister became the summer’s first stinker. Land of the Lost, starring Will Ferrell, Anna Friel and Danny McBride, earned a sad $18.8 million over the past three days. Although that amount was good enough for third place, the film cost an estimated $100 million to make.
