Going places

TripAdvisor, the website that allows you to review hotels and read about other people's lodging disasters, brings its summer Traveling Movie Tour to Boston Common. Tonight, the website presents a free screening of "Roman Holiday" (with Audrey Hepburn and Gregory Peck, below). Tomorrow, the featured film is "Planes, Trains & Automobiles." The movie tour supports charity organization Suitcases for Kids and local group Rediscovery, Inc., so you're asked to donate a gently used suitcase or duffle bag if you have one. The bags will be donated to foster children and at-risk youths. 6 p.m. Free. Boston Common near Beacon and Charles streets.www.tripadvisor.com/movietour
