The Mammoth Film Festival, an annual pre-Thanksgiving celebration of the cine arts, is holding its four-day run Nov. 15-18. The festival, which will screen 10 films over three days, combines a film competition, market and trade show, and symposiums into one neat package. Screenings will be held at the Welcome Center Auditorium on Main Street in Mammoth Lakes and the Palisades Room in the Grand Sierra Lodge in the Town Center Village. There is no admission fee to see the films, but attendees must register at to get passes.
