Character mistake: Throughout the movie, Carrey's Commanding Officer, who is a Colonel, is called Captain.
Character mistake: Shonte Jr. says he can't figure out of the atomic mass of a deuteron. He is supposedly a genius, but this is chemistry 101. Average people might not know how to calculate atomic mass, but a genius would not make a beginning level error like this.
