Wolfram|Alpha added a new features that "detail U.S. box office data, with information on total, weekend, and in many cases even daily receipts for motion pictures." So if you want to see how a recently released film is doing in theaters, just ask about its box office totals. For e.g., "eat pray love box office". Or maybe you'd like to look back and compare some of the summer's biggest blockbusters.
Try "box office for iron man 2, toy story 3, inception" for a quick comparison; to make it even easier to compare several films released on different dates, click "Show by weeks since release" button to align the movies' start dates. In this case, it's easy to see that although Iron Man 2 had the strongest opening of the three, its revenue also fell off more steeply in the following weeks.
