Deadline reports Rise of the Planet of the Apes screenwriters Rick Jaffa and Amanda Silver have been hired to write the sequel with Spielberg and Kathleen Kennedy both producing.
As of now there are no plot details, but this is the most solid news we've gotten on the potential sequel, and we still don't know if it will act as a franchise reboot to open up for more sequels. This writing duo successfully pulled of a Planet of the Apes sequel, so I'd say they're probably are the best people for the job.
Deadline also says Spielberg won’t direct the fourth film, which shouldn't shock anyone. I’m sure some will still hold out hope that he might change his mind, but don’t be too hopeful.
Spielberg did say last year “hopefully we’ll make it in the next two or three years,” and this hire suggests that timetable may not be too far off, at least if the script turns out well.
Universal is likely testing the Jurassic Park interest pool with their re-release of the first film in 3D next summer on July 19th, 2013. Lets Hope it's not any worse than the third installment, and brings back Jeff Goldblum. But what will we do without Stan Winston and his magnificent effects?
