Tarantino gets his best-ever opening weekend with war flick
The film took $37.6 million (£22.7 million) at the US box office, bettering the $25.1 million taken for Kill Bill: Vol 2 in its opening weekend back in 2004.
It replaced Peter Jackson's low-budget alien drama District 9 at the top of the US film charts, leaving it to slide down to second place, while GI Joe: Rise of the Cobra ranked third and romantic flick The Time Traveler's Wife came in fourth.
Julie and Julia finished off the top five, while two new entries made an appearance in the rankings, family film Shorts which came in at sixth and Post Grad which debuted at number ten.
Tarantino's latest offering also proved popular with a global audience, taking a further $27.5 million across 22 nations.
Inglourious Basterds stars Brad Pitt, Diane Kruger, Melanie Laurent and Christoph Waltz and is set in Nazi-occupied France.
