In the PETER PAN that I am currently co-directing Peter is played by a boy in 5th grade, so he is about ten years old. I have not told the Flying by Foy people that yet so I hope they can still fly him. And it is only for one week. Then again, look at the stamina of those BILLY ELLIOT boys! They do their own flying, though they don't do 8 shows a week. Perhaps the only way to do a boy as Peter on stage for a long run is to go the BILLY ELLIOT route and cast 3 or 4 boys to alternate.
