A few years back Soshana Bush, the 20 year-old blonde female lead in Damien WayansDance Flick (Paramount, 5.22), attended Redwood High School in Larkspur, just north of San Francisco, in the same class as my son Jett. They didn’t run with the same crowd, Jett says, but they half knew each other. So it seems appropriate that Jett should catch a screening of Dance Flick in Manhattan this week and review it for Hollywood Elsewhere.
