Clone Wars.

A few years ago, I read this article about how certain themes in movies seemed to attract the attention of script-writers at the same time. It was not the matter of competing, since usually scripts are kept in the dark until actually bought, but just that certain times found certain themes well adaptable for movies.
Some ideas just didn't follow through. When Guy Richie casted Robert Downey Jr. as Sherlock Holmes, Sacha Baron Cohen was cast in the same role by someone else. That project was cancelled, but Richie's movie is now getting a sequel, and BBC made a magnificent modern-take mini-series on the story just last year (to be followed up this Autumn). Some exampel's that did come out within just a few months from eachother, are:

Full Metal Jacket - Platoon.
Near Dark - The Lost Boys
Thin Red Line - Saving Private Ryan.
Antz - A Bug's Life.
Capote - Infamous.
Clash of the Titans - Immortals

And every couple of years there is a new version of some Austen/Dickens/Brontë book, or a new version of Three Musketeers or perhaps Robin Hood. Fairytales as well, will never die. Especially now that Hollywood keeps spouting out remakes of all these 40's-80's movies, you know they won't be laying off the classics.

So why did I suddenly think of this tonight? Well, within the next few months, cinemas in Sweden will show a re-make of Brontës Jane Eyre, Dumas The Three Musketeers, a Robin Hood came out last year and a Red Riding Hood this year (see what I'm getting at?).
For next year, as fortold on IMDb (I love that page), there will be both an at the moment untiteled Snow White-project with Sean Beam and Julia Roberts, as well as Snow White and the Huntsman with Charlize Theron, who looks pretty amazing in her getup.

But... Really? Even if you are running out of ideas and looking to old stories is your way to go, how does Hollywood succeed in only looking in the same direction at the same time?
Rejuvenate your buisness or get out.
