Brad Pitt, Inglourious Basterds

There was nothing inglorious about the opening of Quentin Tarantino's latest flick.

Tarantino's World War II action film, Inglourious Basterds, took the top spot at the weekend box office, raking in an estimated $37.6 million, according to The Hollywood Reporter. The film's opening outdid Tarantino's previous best outing, Kill Bill Vol. 2, by more than $12 million. Basterds also took an additional $27.1 million overseas.

Last week's champ, District 9, earned an additional $18.9 million for second place, bringing the film's total haul to $73.5 million. The rest of the top 5 was rounded out by G.I. Joe: The Rise of Cobra ($12.5 million), The Time Traveler's Wife ($10 million) and Julie and Julia ($9 million).

The weekend was up 31 percent from a year ago, but newcomers Shorts and Post Grad performed below expectations, earning $6.6 million and $2.8 million respectively.
