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. Using new technology to restore dozens of hours of footage captured a century ago on the Western Front, Jackson gives audiences an unusually human glimpse into life on the front line.
