Basil77, how could you?! This is a great New Year movie!
It has almost nothing in common with the book, but it's good on its own.
Yes, I watched Charodei (the Sorcerers) first when I was a little boy, but read the book much later. I didn't even know they are related (I don't watch titles usually). Of course, they have nothing in common and if you don't know it, you'll like both.
