Here's what's going on today (Saturday, Feb. 2): Appropriately, Bill Murray's Groundhog Day is tonight's special screening at the Lucas Theatre. PULSE continues at the Jepson Center with Family Day (just what it sounds like) from 2-5 p.m. Some clown named Robin Williams shares the stage with David Steinberg at the Johnny Mercer Theatre. Willy Wonka has two shows at the Savannah Children's Theatre. And it's the final day for the Savannah Jewish Film Festival. And catch red-hot swamp blues singer/pianist Beth McKee at Randy Wood Guitars.
