42ND STREET Bebe Daniels, Ginger Rogers, and Ruby Keeler star in this 1933 Warner Bros. musical about the backstage goings-on behind a Broadway musical. With Busby Berkeley musical numbers and a knife-sharp script set in and shaped by the Depression, it's one of the granddaddies of the ridiculously fecund 1930s American filmmaking. You've got to come back a star. At the Charles Theatre at noon Jan. 2, at 7 p.m. Jan. 4, and 9 p.m. Jan. 7.
