I remember it well, the text said.

I literally had anUntouchablesposter on my wall.

He came out and hung around with the extras between setups.

It was a big deal for us, because he had the exact career that we wanted.

He was very nice to us.

I actually started walking my life backwards for a second, he says.

My eyes were full.

I didnt feel empowered…I just felt like, I need to do better.

Im gonna do better, Im gonna find other movies.

I thought, I need to go forward.
