But is it true?
Yes, kinda. I will say that the film does take place in the Discworld series which is where the Mort book (fourth in the line of books, btw) takes place, but remember that this is an adaptation that won't necessarily be literal (no film adaptation really is). I got confirmation from the Bothans of this. The hero of the book shows that this is an entirely different kind of story than Walt Disney Animation Studio has told before, but it does have a princess in it. Remember that this is early in the process and things can change. It's at least three years before it will come out and the animation process is a long, bumpy and slow road.
