Sure, exploring bold new frontiers of cinema is important , but there's a lot to be said for seeking solace in a known quantity. That's why after a long day I'll throw Clerks into the DVD player for the umpteenth time, or maybe give Superman another spin. Sometimes you just want to deal with something you know, know what I'm saying? This week's quintet of trailerly goodness takes a peek at films with a comforting sense of familiarity.

Saw IV
Hey, it's another Saw sequel! Personally, I do not get a warm sense of recognition from this, but obviously some people do since there's been a new entry in the franchise every Halloween since it all started back in 2004. There's a new trailer (in glorious HD!) that shows off a little more footage than the domestic theatrical teaser I mentioned a few weeks ago. The villainous Jigsaw does the voice over, despite looking pretty dead when he's seen onscreen. There's also a cluster of quick cuts that will leave your head spinning. This one's not for me, but don't let that stop you from enjoying it.

Hey, it's that guy from Elf, Talledega Nights and Blades of Glory, and -- holy crap -- he's naked. Will Ferrell bares nearly all in this teaser for his new movie about pro basketball in the 1970s. It's hard to form an opinion based on less than a minute of footage that doesn't look like it will even be in the final film, but it looks like Ferrell is doing what he's become known for, and that usually makes me laugh.
