Containing the most hot air is Professor Lawrence Wetherhold (Dennis Quaid), and if anyone's in need of deflating, it's him. He's a English Lit professor who's lost his passion for teaching and literature (if he ever had it). He's also most definitely lost any and all interest in his students. He forces them to wear nametags since he can't remember any of them, even ones he's had in his classes more than once. He's pompous, acerbic and generally oblivious to all around him. His son James (Ashton Holmes) has moved out of the house in order to escape the infectious atmosphere there. Now he secretly writes poetry in his dorm. His sister Vanessa (Ellen Page) has tried to clone herself after her dad. She's an overachiever who looks down her nose at all the stupid people in the world. She also tries to fill in the gap left by her late mother. Wetherhold's wife died years ago and he still hasn't recovered from the loss.
