Well dan being 21 playing a 17 yr-old isn't bad compared to what they did in the Percy Jackson & The Olympians- The Lightning Thief movie. In the movie, they changed the starting age from 12 to 17, they made Grover African- American and changed his personality, they mad Annabeth brown haired (supposed to be blonde) bluish-grey eyes (supposed to be stormy gray) and the actress is 24.

I was pretty *miffed*
