Want to know more about what it took to create "The Last Battle"? Here are some cool behind-the-scenes facts.

“The Last Battle” boasts an enormous cast. More than 30 principal speaking roles are featured, including a unicorn, an eagle, a dwarf, a dryad and a ginger cat. The cast also includes "reprise" appearances from several creatures from earlier adventures, such as Reepicheep the valiant mouse, Mr Tumnus the faun, and Fledge the flying horse. And to add to the many casting challenges, the book called for grown-up or older versions of several human characters, including Polly and Digory.

After a tiring search for an actor to play the role of the evil Tash, the Radio Theatre® team found the perfect one right under their noses. Andrew Sachs, the voice of Puzzle the donkey, changed his voice so dramatically that nobody could believe it. From the same mouth came Puzzle and Tash — an amazing performance!

"The Last Battle" voice tracks were recorded in 1998 and were not touched again until the edit began in the winter of 2001. Post-production on the other Chronicles of Narnia took so much time that post-production on “The Last Battle” couldn’t begin until then.

In production itself, the entire cast and crew felt an extraordinary spiritual impact in the studio while enacting the climactic scene of “The Last Battle.” A number of them portrayed the various characters and creatures choosing whether to walk through the doorway into Aslan’s country. Some looked at Aslan and were so afraid that they fell away into the shadows. Others looked at him with love and walked through. The symbolism was clear to everyone in that moving, powerful moment.

Production engineer Mark Drury logged more than 1,500 hours on the sound design and mix of "The Last Battle.” But you've gotta have some fun! Here a couple of photos of Mark (below, left) working with Dave Arnold to help bring "The Last Battle" to life.

The Radio Theatre® adaptations of the Chronicles of Narnia include 19 CDs containing more than 22.5 audio hours.

The entire production process for this series, from the beginning of the contract process to obtain dramatization rights to the final mix of the final episode, has lasted six years.
