This is a direct quote from himself:
“I recently finished playing Saruman the White, the Wizard in ‘LORD OF THE RINGS’. It has always been a dream of mine to bring to the screen the marvels of this wonderful work and this has allowed me to take part in a production which could well be the pinnacle of my acting career. I can’t talk about it more than that, so you’ll have to wait and see!”
Thanks to Arathorn for that.
