Chloe Moretz is a child actress most recently famous for starring as the potty mouthed heroine of Kick-Ass. The movie is ultra-controversial. Chloe was just 12 years old when she filmed that movie. A lot of people had a hard time accepting all those lines coming from the mouth of a child. However, I have read countless times that her mom read the script before she allowed her daughter to read it and gave the okay. That is enough for me. If Mom is okay with it, then who are we to decide otherwise?
Anyways, controversy aside. This kid has been busy. Check her IMDB page if you don't believe me. She has been working in the business at least since 2004. She worked with Ryan Reynolds on The Amityville Horror and Jason Lee on My Name Is Earl in 2005, did the voice of Young Penny in Bolt in 2008, and was in (500) Days of Summer from 2009. Since Kick-Ass, she has 2 other movies that have come out (Diary of a Wimpy Kid and Let Me In) along with 8 other projects in the works. For 13 years old, she is incredibly busy and very talented!
