Redlight, Greenlight.

One of this summer's guilty pleasures has been watching the HBO reality series, "Project Greenlight." This year's independent-movie-making contest picked separate winners for the script and the director. Or, as it turned out, co-directors. And to create some artificial drama, the screenwriter stayed around to have input on the directors' choices and changes. (Okay, officially the writer was around to make verbal some of the directors' thought processes. But it was really to inject some conflict.) And some of the other time constraints seemed artificially tight, to create additional tension and thus better TV.

When you get past the artificial pressures, though, you get a good look at the real-life problems in film-making: casting, finding locations, getting shots set up and filmed within the film-making day, getting the right material to be edited into a complete film, making sure the suits at the studio are happy with the final product so they'll market it. Great fun. I'll recommend it. Can't yet recommend the movie they're making; it'll be released in a couple of weeks. And, of course, no telling how widely it'll be released. But the original script is pretty good.
