Judy Greer

I remember my choir teacher in high school told me, 'When in doubt, sing loud.' I'm a terrible singer, but I always auditioned for the musicals, and would get cast in them because I really would just put it all out there. That was really good advice, and I think it works for everything, not just acting.

The truth is, if I was maybe better or funnier or prettier, wouldn't I have starred in a movie? I can see it objectively as a businesswoman - if no one's buying your product, then there's not a desire for it.

Working on 'Austin and Ally' has been an absolute dream! We literally have fun every single day! Whether it's scaring each other or singing together or just hanging out in each other's dressing rooms, the cast and I are super close! I feel really lucky to be with everyone on our set!

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
