Continuity mistake: Just as the moderator finishes asking Lydia "Do you have a slight self-consciousness about the incredibly varied things that you've accomplished", he places his right hand on the armrest, but when the shot cuts, his right hand is over his lap. (00:09:25)
Character mistake: After the math club students, in unison, cited pi to 3.141592, Percy continued with "65839" - but only the "65" are correct. He should have said "65358..." before being cut off (or "65359" if he was rounding up the last "89793238"). Even though the movie is classified as a comedy, Percy was showing off, but he was wrong. Charlie, Math Club Advisor, also committed a mistake because he stopped Percy by saying "Percy, we got it. Good" (as though Percy was correct). (00:04:29)
Continuity mistake: When Priscilla meets Elvis in Germany the position of the letters on the bed and of the papers scattered on the floor change positions between shots.
Continuity mistake: While driving to Harper's house, Jordan did not have the sun visor down, but it was down when she was backing up after she passed Harper's house, #237. The sun visor was not down when Jordan was going down the driveway to the house. (00:17:15)
