Andrew Adamson, the director of Shrek, says he plans to take the animated techniques used in the movie even further when he directs an animated version of writer Terry Pratchett's Bromeliad Trilogy. He told the BBC's Web site that he intends to make the characters in the books (Truckers, Diggers and Wings) "as physical and real in the world as we are. ... What I hope for is that every time people walking out of the theater see something out of the corner of their eye -- they will think it is one of the characters from the movie." Adamson also praised Pratchett, whose novels are outsold in the United Kingdom only by Harry Potter writer J.K. Rowling's. "Terry's an amazing writer and has an incredible way of taking things that we know and see on a daily basis and turning them around and showing them to us in a different way."
