Lightweight Will Ferrell vehicle ‘Semi-Pro’ was the number one rental this week. And while it made just $33.5 mill at the domestic box office, Ferrell also topped the DVD sales chart.

The low-rated comedy ‘Meet the Spartans’ came in second in rentals. The spoof movie was mildly more successful at the domestic box office, but did $35 more than ‘Semi-Pro’ overseas. Sadly, no rental box office numbers were provided this week.

The top seller of the last two weeks, ‘National Treasure: Book of Secrets,’ came in second in sales.

Nicolas Cage’s biggest movie yet came in at number one for both sales and rentals last week. ‘National Treasure: Book of Secrets’ grossed over $450 million at the worldwide box office and its grabbing a couple more million in stores now. It pushed last week’s top rental ‘Mad Money’ to the second place, which made another $6.1 million. ‘National Treasure: Book of Secrets’ took in an estimated $8.7 million.

But Disney’s adventure doesn’t end there. ‘National Treasure’ topped the Blu-ray and DVD sales charts too. ‘National Treasure: Book of Secrets’ was the number one Blu-ray, ‘National Treasure’ (the first movie) was number two and they shared the third place with a two-pack.

Indy also makes an appearance. The first three ‘Indiana Jones’ movies took the second to fourth place in the DVD chart. And I reckon most of the viewers went to the fourth installment after that.

Before Steven Spielberg, George Lucas and Harrison Ford will make some money on the new ‘Indiana Jones,’ the studio has to cover its $400 million in expenses the LA Times says. In recent years, more and more bigwigs have opted for a percentage of the earnings, instead of taking an upfront fee.

Paramount Pictures will have to make $400 million to cover its production and distribution fees. After that Spielberg, Lucas and Harrison will start making 87.5% of every dollar made, while Paramount will get 12.5%. Similar deals were made with Jerry Bruckheimer, Johnny Depp and Nicolas Cage on ‘Pirates of the Caribbean’ and ‘National Treasure.’

Of course, we fully expect the new ‘Indiana Jones’ to make more than $400 million. These guys aren’t stupid. They will make 87.5% after that, $1 million per every $1.15 million. One of the main reasons they can do this is because Lucas owns the rights to these properties, while other movies like ‘Spider-man’ are fully owned by the studios.
