(Firstly, I apologize if this is a repeat question.)

Are all of the cast members of 13 strictly thirteen years old? Though I am eighteen and a half (today, actually ), I am often mistaken for and cast as a twelve to fourteen year-olds. I was listening to the music from the show today and thought it was pretty awesome!

I hear they aren't looking for anyone over 15...

If you are 18, there are so many other roles on Broadway that you can audition for. Dont limit yourself to the young child roles. You can certainly play a Mermaid in "The little Mermaid" or one of the many characters in M. Poppins. There are tons of roles open to you. Good Luck!
