I read Inkheart by Cornelia Funke more than three years ago. My main recollection is that I thought it would never end. When the main character escaped the bad guys and then turned around and went back to their lair, I wanted to wring her little neck.
But Book Moot posted a link to a trailer for the movie, and it doesn't look half bad. I know you can't trust trailers, but this one almost looks as if it focuses more on Mo, the father, than on...ah...ah...whatever-her-name-was, the daughter. If that's the case, some fans might be disappointed (it's supposed to be a kids' book, after all), but I won't mind.
I don't mind Helen Mirren as the freaky aunt, either.
