How old do you have to be to audition for a Broadway musical?

Question

I know there are little kid roles, but that's not what I mean. The roles I'm talking about are the supporting and ensemble roles.

Answer 1

Well it would depend on what the play was.  There are plays that have kids playing bigger roles.

But, if you mean "adult" roles...that would probably depend on how you look/sound (age-wise).
