Youth and inexperience were no deterrents to 12-year-old Emily Hagins when she set out to make her first full-length feature, the zombie flick Pathogen. This 2008 documentary chronicles her two-year endeavor from start to finish. With cameras focused on Emily and Mom -- who acts as agent, crew, producer and No. 1 fan -- the film illuminates indie moviemaking challenges and the wonder of being a plucky adolescent to whom anything seems possible.
