According to preliminary numbers, this year's RiverRun International Film Festival in Winston-Salem, which ended this past Sunday, had double-digit growth over last year's festival in both admissions and box office revenues. Total admissions to films, parties and events at this year's festival were up almost 12 percent over last year's number, and box office revenues were up by more than 15 percent. RiverRun doesn't publish attendance estimates, but instead publishes admission numbers, which show how many total individual entries there were into screenings and other events. Box office grosses this year were $81,984, up from $70,995 last year and the highest since 2009. A total of 143 films - 66 features and 77 shorts, representing 35 countries - were shown during the 2013 festival, including one world premiere, "Susie's Hope," a drama filmed in Winston-Salem and based on a true story. The films were selected from more than 850 submissions. The festival also had a record number of sold-out screenings. The number of sell-out screenings is expected to drive up pre-festival ticket sales next year, which currently accounts for more than half of ticket sales.
