Jeff Bayer and Eric D. Snider are both live and in the studio this week for a scintillating edition of Movie B.S. with Bayer and Snider. “Sanctum” — a movie with which James Cameron is somehow vaguely affiliated — is about caves and underwater and stuff, and Bayer liked it more than Snider, although they both gave it the same grade. “The Roommate” wasn’t screened for critics. Wasn’t even screened for the yahoos who go to promotional screenings. Must be awesome! Bayer and Snider also discuss the answers to the QOTW (which two actresses should make a movie together?), and issue a new QOTW: What three films would you program for a mini-marathon for Valentine’s Day? Also, a rousing and controversial edition of Pitch Me involving race relations and mad scientists.
