Being that I haven't read the books so not sure what to think about this...

So it looks like Twitter really is becoming a good resource for updates. Producer Frank Marshall wrote a few updates on his Twitter (twitter.com/LeDoctor) recently related to Bourne 4, the in-development fourth sequel in the Jason Bourne series. "Bourne 4 is in the works for Summer 2011," Marshall wrote. He later added in another update that "George Nolfi is the writer of Bourne 4, [and he] should have a draft by June," mentioning that, "it really takes long to get these scripts right!" Of course! And especially on something like this, I'm more than happy that Marshall is taking as much time as he needs and not rushing into it.

Our last update on Bourne 4 hit in October, when it was officially confirmed that George Nolfi (of Ocean's Twelve, The Sentinel, The Bourne Ultimatum) was writing the script and that Paul Greengrass was back on board to direct. Before that, our last headline stated "Fourth Jason Bourne Film on Track for 2010", but obviously it will now be 2011, which means Nolfi will finish up this script soon and they'll shoot next year. Marshall said previously they'll probably take Bourne "down south" to South America in this fourth film, but story details aren't fully finalized, and with re-writes still occurring, who knows where they'll end up?
