PARK CITY — Killing an exaggerated version of North Korean leader Kim Jong Un in Sony's controversial comedy "The Interview" wasn't a problem for actor James Franco but he found challenges in playing real-life murderer Christian Longo for thriller "True Story." "He's probably the worst person that I've ever played, just because I have such a great family and there's just something so horrible about killing your kids. So I have very little connection to him," Franco told Reuters. "True Story," which premiered at the Sundance Film Festival on Friday and will be released by Fox Searchlight in US theaters on April 10, is based on the memoir of former New York Times journalist Mike Finkel, who formed a friendship with a murderer who used his name as an alias. — Reuters
