Meg Hamel has always had a novel philosophy for the Wisconsin Film Festival; make it a festival, featuring films, located in Wisconsin. That sounds obvious. But at other film festivals like Sundance, South By Southwest and Tribeca, showing movies is just one part of the experience. Those fests also include a wealth of festival parties, music performances, screenwriting competitions, celebrity sightings, filmmaking classes, swag giveaways and other side events. Not so at the Wisconsin Film Festival, which runs Wednesday, March 30, through Sunday, April 3.
