Michael Jackson’s This Is It slowed down considerably, but was still good enough for a distant second place, hauling in $13.1 million. The Men Who Stare At Goats wasn’t far behind at number three, with $12.7 million, while The Fourth Kind was close behind that, at $12.2 million.

Paranormal Activity was the first movie to finish with less than $10 million, hauling in $8.2 million nearly two months after its initial limited release and a month after it first hit theaters nationwide. The Cameron Diaz vehicle opened poorly with $7.5 million, but fortunately only sported a $25 million budget.

With Monday total not yet in, Spielberg-Lucas-Ford action flick has so far grosses $126 million domestically and $146 million overseas, for a grand total of over $272 million combined; not bad for a movie that had a production budget of $185 million.

Prince Caspian, the second film in the Narnia Chronicles, based on the series of children’s stories by C.S. Lewis, did well enough to retain second place, but at $23 million, saw a huge, 58-percent dropoff from its debut week. Boasting a production budget of $200 million, Prince Caspian’s two-week total is $96 million domestically, and $22 million overseas, for a disappointing two-week total of only $118 million. This could make it difficult for the sequel to make its money back prior to DVD release.

That’s not a problem for Iron Man, which held on to the third spot in the box office race with an additional $20 million domestically. In release not for over three weeks, Iron man has taken in $257 million domestically and $228 million oveseas, for a staggering total of just inter $486 million; considering the film’s relatively slim $140 million budget, Iron Man stands now shoulder-to-shoulder with Spider-Man as one of Marvel Studios’ most profitable franchises.

What Happens in Vegas made just over $9 million in fourth place and then there was a huge dropoff as Speed Racer couldn’t even draw $4 million to take fifth place. Speed Races has only barely topped $36 million, contrasted to its $120 million budget, guaranteeing its stink-bomb status in this summer movie season; even with foreign box office added in, the film has barely made half of its investment back, at $61 million, and with business dropping like a rock, the best hope for producers to make their money back on Speed Racer is DVD/Blu-Ray sales.

This coming weekend is likely to be the least competitive of May, as Sex and the City and the thriller The Strangers are the only two new entries; both flicks seem unlikely to unseat Indy 4, and depending on the dynamics of the weekend, could potentially have trouble unseating Prince Caspian and Iron Man from the Top 3 spots as well.
