The 54th annual Rochester International Film Festival opens April 19 and runs through April 21 at the Eastman House Dryden Theatre, 900 East Avenue. Thirty short films including animations, documentaries and narratives will be screened in four different programs, at 8 each night, with an additional 4 p.m. matinee on April 21. Admission to the Rochester International Film Festival is free, though donations are accepted. The festival, formerly known as Movies on a Shoestring, began in 1959. A group of Rochester-area film enthusiasts operate what is now the oldest continuously held short film festival in the world. Each festival includes a wide variety of original and imaginative works by filmmakers from around the world. The 30 films include shorts from nine countries, including 14 films from the United States, seven from France, and others from Iran, Germany, Ireland, Australia and several other countries.
