During the making of the Lord of the Rings trilogy, film crews used an iPod as a "modern-day Ring-bearer".

According to a feature in The Hollywood Reporter, director Peter Jackson used an iPod to help him get daily shots and sequences halfway around the world.

The media was first transferred from the New Zealand-based Weta Digital crew to Pinewood Studios. The shots were then uploaded to Jackson's 30GB iPod and couriered to his home.

Once downloaded from his iPod, Jackson would view the 1K-resolution QuickTime files on an Apple Cinema Display using his G4 laptop. This set up was mirrored in New Zealand.

Visual effects supervisor Jim Rygiel said: "What the iPod gave us, since we were in such a high-speed mode at that time, was just a real quick turnaround. We could show Peter many, many iterations and get shots to the point where we were 99.9 per cent sure that when we put it on film, it was going to be final."

During the course of two movies and four months, the iPods stored and served up nearly half a terabyte of digitized footage from The Two Towers and Return of the King, according to the report.
