Mr. Rooney


After the suicide of the teenager Allen Clark, his family decides to move from Chicago to the quiet Cradle Bay Island seeking a peaceful life for the siblings Steve and Lindsay Clark. When Steve joins the local high-school, the outcast Gavin Strick befriends Steve and introduces his also rejected friend Rachel Wagner to the newcomer. Gavin exposes to Steve in the refectory the punks, the nerds and the different tribes of the school and he defends the weird theory that a sinister force changes the behavior of the annoyingly perfect "Blue Ribbons", a group of good students that wear identical jackets and gather in the Yogurt Shoppe. Further he tells that he had witnessed the blue ribbon Andy Efkin killing their schoolmate Mary Jo that is missing and the local Officer Cox covering the murder. Steve does not believe on Gavin words, but when his friend is submitted to the treatment of Dr. Edgar Caldicott and immediately changes his behavior, joining the Blue Ribbons, Steve and Rachel ...

Did You Know?


The personifications of good and evil in the town are named Newberry and Caldicott, which happen to be the names of the two prestigious book prizes awarded by the American Library Association for Excellence in Children's Books (one for novels and one for picture books). See more »


In the early classroom scene with Mr. Rooney, the word "tomorrow" is misspelled as "tommorrow" in "Tomorrow's Assignment" on the chalkboard. It's doubtful that an arrogant English teacher would misspell this word. See more »


Rachel Wagner: Listen, the last ferry leaves at eleven thirty. Just tell me you have a razor plan?
Steve: I am making this shit up as I go.

James Marsden and Katie Holmes star in this teen thriller involving teenage kids getting brainwashed! I expected a fairly bad movie but I didn't mind this flick! It was an enjoyable yarn that didn't try and go overboard at the end!

Although I can't say I'd rush out to see it again, I think it's worth a look! Because I wasn't expecting much and I was entertained for 90 minutes. Plus I liked the whole concept! *** out of *****!
