I Get Outsmarted by a Second Grader

I haven't seen "Up", but from the trailers the movie looks suspiciously like a children's book from 1990, titled "Wilbur's Space Machine".

I read the book this morning for Rolling Readers. Before beginning it, I told the kids I thought the story seemed a lot like a new movie. It only took until page 6--which showed a square porched house, an old man, and a nuisance neighbor boy--for a girl to pipe up with "Up"? On my first read through, it had taken me until page 13.
