Couch theater — DVD previews

Make them or break them, New Year’s resolutions are a tool to set good intentions for the year ahead. For instance, one of mine: I resolve to spend more time lounging about on the couch watching movies (hey, it’s a pretty easy resolution to keep). If you need some resolution motivation, it’s never too late! Take a look at the four major themes below and draw some inspiration, then clip and save this column for late January, when you need some cinematic encouragement to carry on! Making Physical Changes “Heavyweights” features a bunch of kids sent away to weight-loss camp where the new director (Ben Stiller) is too overthe-top. Naturally, the kids stage a coup. In “GI Jane,” the first female recruit (Demi Moore) for the Navy SEAL program gets incredibly tough -- and incredibly buff. Jillian Bell plays Brittany, a woman who takes up running after a routine checkup reveals the damage her profligate existence has unleashed, in “Brittany Runs a Marathon.” Going Back to School

In “Billy Madison,” Adam Sandler is heir to a hotel chain, if he can show he actually deserves the diplomas that Daddy bought. To prove he has the smarts, he has to quickly retake every grade. Self-made man Thornton Mellon ( Rodney Dangerfield) sends his much-loved son off to college, then follows him “Back to School” to make sure he has the full experience. Kevin Hart and Tiffany Haddish square off as student and teacher in “Night School,” in which Hart plays Teddy, an obnoxious salesman who needs his GED in order to keep his lavish lifestyle illusion alive.
