Bad Chemistry was released in the year 2007。Bad Chemistry is also called as Dårlig kjemi。

The school day is dramatically overturned for the 11-year old boy wonder and chemical prodigy Frederik when Ulla, a hippie-like substitute teacher replaces his rigid favorite teacher. Homework and assignments are replaced by playing games and classes are set outdoors. Also, Ulla seems particularly preoccupied in eliminating all the children's "inner trolls". Frederik feels forced to fight back.
