Joblo.com reported recently that “Saw IV” has begun casting. Lyriq Bent who played Rigg in the Saw 2 and Saw 3, and Gilmore Girl’s Scott Patterson have both signed on.

Director Darren Lynn Bousman tells Joblo.com, “Yes Lyriq Bent is in fact returning… He is a great actor – and am very excited to be working with him yet again – on part IV. The story is much darker – more fucked up – and much more psychological! Oh yeah and there is some blood too!” Allegedly the “SAW IV” plot revolves around the character Rigg.

Production begins April 16, 2007.
