A Chronicle Review article featured Eran Preis, associate professor of film and media arts at Temple, and his latest documentary, "Jonathan's Return." Preis would be thrilled if festivals were to feature his film, but is just as concerned with having his account of his 33-year-old son's battle with schizophrenia shown at homeless shelters and support-group meetings. "There's a real need for people to know that you can talk about it, and you don't have to hide it," Preis said.
