14. The Girl Next Door (2004)
Life as a straight-A high school student with political aspirations can be so mundane. So it's easy to see why Matthew (Emile Hirsch) falls in love with a former adult film star when she moves in next door. Well, former until her old producer comes back and convinces her just how mundane her new life is.
Now this straight-A student is poppin' E pills, gettin' slapped around by the producer, and almost ruins his chance to get into his dream college while trying to convince her to stay away from random cock. Tireless work, given her profession.
