OK, so it is a cartoon movie about mice. Kind of puts it on my mental back burner. Then you see the cast:
William H Macy
...you have my attention.
And I know Im a loser, but it gives me such glee when actors from the Harry Potter movies work together in other films (Hermione and Hagrid in this one, Ron and Mrs Weasley in The Driving Lesson, which I HEART!)
