The White Sands International Film Festival returns to sunny Las Cruces on Wednesday, Sept. 4, with another four days’ worth of cinematic discoveries. This year’s highlights include: a lifetime achievement award for guest of honor Lou Diamond Phillips, the world premiere of the locally shot comedy Roswell FM and one of those increasingly popular “48-hour film” competitions. Noted character actor Christopher McDonald (Happy Gilmore) will be teaching an acting workshop. There will be a panel discussion on “Writing For Film” featuring C.M. Bratton, Kerry Valderama, David Spence, Amy Lanasa and Mark Medoff. To top it all off, dozens of features, shorts, and documentaries will be shown Wednesday through Sunday at the Cineport 10 theater.
