Chloe Grace Moretz's brother is her acting coach

Chloe Grace Moretz has her brother to thank for roles in popular films like Hugo, Kick-Ass and Dark Shadows - he is her acting coach.

The 15-year-old rising star broke onto the scene in 2009's (500) Days of Summer, and since then she has teamed up with such veterans as Martin Scorsese, Nicholas Cage, and Johnny Depp.

But, Moretz refuses to take full credit for her success - her sibling Trevor has taught her everything she knows.

She tells InStyle magazine, "My brother Trevor went to the Professional Performing Arts School in New York. I was five or six at the time, and I would hear him practising his monologues over and over, and I would recite them to my friends and family. I begged my mom to take me to auditions, and my brother was like, 'If you're going to do this, let me show you what I know.'

"I started getting booked, and eventually he became my full-time acting coach. He travels everywhere with me."
