Movie directors do it all the time for obvious reasons. Rachel McAdams was 27 when she played a 16 year old on Mean Girls. I don't think an actual 16 year old would've pulled off the part very well unless they were very mature for their age.modelzsuck said:Yeah I love these books I am just finishing the third one, I hate how they put ppl who are too old in the roles and ruin the book like how I think Delta Goodrem in Hating Alison Ashley is going to ruin it.
