Here is the trailer for "Happy Valley," the upcoming documentary that examines the circumstances behind the crimes of former Penn State assistant Jerry Sandusky, who was convicted in 2012 of 45 counts of sexual abuse of young boys.
The film was written and directed by Amir Bar-Lev. His earlier work included the 2010 documentary "The Tillman Story."
"Happy Valley" is scheduled for release on Nov. 19. Los Angeles Times film critic Kenneth Turan gave the documentary a favorable review at the Sundance Festival.
