When you're compelled (by money and ravenous fans) to churn out another Saw movie every single year, you don't have much time to a) write a script, b) hire actors and c) keep everything a big fat secret. Case in point: It's been widely mumbled that David Hackl (production designer on Saw 2 and Saw 3) would be the one settling into the director's chair for Saw 4, and that seems a pretty good move: Get some fresh blood in there, but have it come from someone already inside the Saw family. (Plus it's probably pretty difficult to get an established director who can take a gig and start shooting "like, next month?")

And now comes additional news. IGN Movies is reporting that Ja Rule will appear in Saw 4, but only in the first scene. (And we all know what that means!) Additionally, some guy who allegedly read the Saw 4 script (which we believe was written by Feast scribes Marcus Dunston and Tom Fenton) claims that Angus MacFadyen's character plays an important role -- but Angus Mac hasn't technically signed on for the sequel at this time.

Looks like production is scheduled to begin next month in Toronto, so we should have a lot more information within the next few weeks. In the meantime we can all sit down and enjoy our Saw 3 Unrated Version DVDs, a platter that's presently poised atop the DVD sales AND rental charts. (Interesting note: Not only was Saw 3 the top-selling DVD last week, but its arrival gave Saw and Saw 2 fresh life; they're both back on the Top 20 sales chart this week!)
