When I was in high school, I was rather consistently cast as a young male:
Edmund in The Lion, the Witch, and the Wardrobe
Conrad in Much Ado About Nothing
Musicals, I was usually in the chorus, but when we did The Fiddler on the Roof, I finally got cast as a female lead, Shaindel (not sure I'm spelling that right; she's Motel's mother). Consequently, I was awarded the Has-Finally-Been-Cast-in-a-Female-Role Award as a joke at that year's drama banquet.
Now I do amateur voice-acting. I haven't gotten many roles, but so far my niche seems to be "Voice Over the Intercom" and "Serious Wise Woman." I did get a small part as one of the ghost children in an adaptation of
Coraline, though, so that's a start.
