Auditions

I find it interesting, that time after time, when audition notices are posted, that they fail to mention cast requirements. Surely it would be more practical to list the age and sex of the cast required,there and then, than to have those that are interesed, ringing the director, only to find that there is no part in the play for an 80 year old actor, or to be asked by the director "Are you a 20 year old female,with red hair"
