Apparently, the writers for the tv show, Alias are finishing up the script for this one. My question though is, is it worth the effort?
I enjoyed the first movie, but the second one was too over-the-top for my liking, with special effects are stunts taking a bigger role than a decent script (and what also sucked was Metallica featuring on the soundtrack).
Filming is only set to being next year though, so don't be surprised to see another team of people working on a script.
