As an example of why studios, before they inevitably die like the dinosaurs, are going to stick to superhero-type movies* or pre-planned and bought trilogies, read this.
[*By which I mean, films in which the central character or concept is more important than a star, so that the power of ‘stars’ diminishes over the years.]“Indiana Jones? Funded by Paramount, but to get the movie made, they gave away 87.5% of the movie to Lucas/Spielberg/Ford after breakeven. So if the film makes $500 million worldwide, no one makes anything, except for Paramount’s and the producers’ overhead costs. But if the film makes $1 billion worldwide, Paramount will make about $70 million, while L/S/F takes home over $450 million. And this is before DVD and other ancillaries.”
In other words, there’s almost no way possible that Paramount, for their investment and risk, could make enough from this film to rival what they could make from, say, an Iron Man-type movie in which you wouldn’t have that sort of insane profit participation. All this will buy Paramount, even if the film is huge, is small profits and a hit film on their official tally sheet at the end of the year.
This is why we’ll probably see more trilogies, as Iron Man is planned to be. (Iron Man, Iron Man II and The Avengers.) You lock in the talent in advance, with escalating pay of course, but not the insane sorts of monies the talent above were able to demand. As well, if you plan a trilogy format in advance, you can help stave off the drop-off in quality that comes from just starting from scratch with each movie.
If the first film bombs, you pay everyone off and move on. If it hits, however, you (the studio, that is) make rather more money. If the trilogy is so huge as to require more movies after that, you wait five to ten years and then hire a whole new cast to revive the character. Again, the thing is that the character is what draws audiences, not the actors. Look at Bond, Dr. Who, Batman, etc. When Tobey Maguire tried to hold up the studio for more money, they instantly threatened to replace him. And why wouldn’t they? Wisely, Maguire backed off.
The whole article the pull quote above is pulled from can be found here. It’s simply essential reading for anything interested in the nuts and bolts of the film business.
A hat tip to Libertas for putting that up.
