My Quick Picks for roles in this movie.

Verne Troyer as a gnome rogue.

Angelina Jolie as some kind of Night Elf Priestess (so geeks around the world can continue their masturbatory fantasies)

Bruce Campbell as the Human Mage (for sheer badassedness)

John Rhys-Davies as a Dwarf Warrior (cmon, he had Gimli nailed)
