Peter Jackson on His New WWI Documentary, a Painstaking Labor of Love

Academy-award winning filmmaker Peter Jackson is best known for his big-budget fantasy trilogies based on J.R.R. Tolkien's The Lord of the Rings and The Hobbit, which he made over the course of nearly 15 years. Now the New Zealand-based director is making his mark on a decidedly different genre with a documentary about World War I, They Shall Not Grow Old.
