Business was a-boomin for Quentin Tarantino's two-and-a-half-hour war film in its opening weekend. Inglourious Basterds had no trouble taking the top spot at the box office with an impressive $37.6 million estimated take in its opening weekend. The film was showing in 3,165 theaters and scored a hefty $11,881 per-screen average. The film earned just over half of its $70 million budget in its first weekend in theaters and, with the summer season winding down, it should do healthy business in the fall season.

Some holdovers showed some promising endurance this week as well, with District 9 taking second place with an estimated $18.9 million, dropping just 49% from last weekends tally, with a cumulative gross of $73.4 million after 10 days in theaters. G.I. Joe: The Rise of Cobra and The Time Traveler's Wife showed its legs as well in third and fourth place with $12.5 million and $10.02 million respectively. Aside from the Basterds, though it wasn't the greatest weekend for the other new releases.

Robert Rodriguez's Shorts could only manage a sixth place finish with an estimated gross of $6.6 million. The film was in almost as many theaters as Tarantino's Basterds (3,105), but only took in a meager $2,126 from those 3,105 theaters. The only other film playing wide, or semi-wide, was the Alexis Bleidel comedy Post Grad, which took in just $2.8 million from 1,959 theaters for a dismal $1,429 per-screen average. Still, it wasn't nearly as bad as X Games 3D: The Movie which took in just $800,000 from 1,399 theaters for a horrendous per-screen average of just $572.

Next weekend is the last weekend of summer and we close out the season with a few new sequels and a new take on Woodstock. H2: Halloween 2, The Final Destination and Ang Lee's Taking Woodstock all battling for box office supremacy to end the summer with a bang. Check back next week to see who triumphs when all of the box office dust has settled.
