Inspiring people to make small changes that have big results is the goal of a film festival that returns to Lake Tahoe this week.The Eighth Annual Wild & Scenic Film Festival takes place March 8 at MontBleu Resort Casino & Spa.Kay Ogden, associate director of festival sponsor Sierra Nevada Alliance, said she hopes the films inspires people to make little changes to help the environment. Little changes made by a lot of people can end up making a big difference, she said.In conjunction with South Tahoe Refuse, this year's festival will be a zero-waste event for the first time, Ogden said. Like previous years, the festival will include local storytellers.This year's festival includes “Cali Rush,” a movie by South Lake Tahoe filmmaker Mikey Wier. The multi-sport adventure film premiered in December and highlights California's outdoors and the diverse recreational opportunities it provides. Wier is also scheduled to participate in a question and answer session at the film festival.Wier's films have appeared at the festival before, and his growth as a filmmaker is on display in “Cali Rush,” Ogden said.“His films are just beautiful,” she said.The film festival serves as the largest fundraiser for the South Lake Tahoe-based Sierra Nevada Alliance, a network of grassroots environmental groups in the Sierra Nevada.The film festival started as a single event in Nevada City, on the west slope, in 2003. The South Lake Tahoe festival is part of a tour that has grown to include dozens of events around the country.
