Though I'm dreading Spider-Man 4 with the power of a thousand suns, I'm tentatively OK with the notion of a fourth Bourne movie, mostly because a muscled-up Matt Damon is always cause for celebration. But the news in today's Hollywood Reporter about another screenwriter coming on for the project is reason to believe, well, maybe a trilogy would have been enough after all.

Josh Zetumer has been hired to write an entirely new script for the film, after original writer George Nolfi got wrapped up in preparing his directorial debut The Adjustment Bureau, also starring Damon. Instead of tweaking Nolfi's script, Zetumer will write an entirely new one, which will either be used for the film or meshed with Nolfi's script. Doesn't sound like a bad idea in theory, but just look at THR's list of other films that have used this tactic; Fantastic Four: Rise of the Silver Surfer, Star Trek: Generations, and that classic of cinema, X-Men Origins: Wolverine.

Now up to this point the Bourne series has distinguished itself by being smarter than virtually ever other franchise out there, so don't despair just yet. They're hoping to keep Nolfi involved in the process, and he's the smart guy who came up with The Bourne Ultimatum. Still, it's hard not to wonder if, after three films done well, the wheels might be falling off this time.
