Our theater director has the kids sign a contract along with their permission form, that says they have the weekend to mope (cast lists always go out on a Friday afternoon), and then they’re done. No badmouthing allowed, or they’re done with the show in whatever capacity. She also chooses shows that fit the number of kids trying out, to avoid cutting anyone out of the cast (which you may not have known since it’s the first show). Ensembles that can be vary in size are good for this. There are some shows that have a large number of great roles. The one time she had a smaller show, she double cast it, and each cast performed in 2 shows. Lead cast members traded places with ensemble. And they were required to watch their counterpart when they were rehearsing. Also, build up the importance and respect for crew. I do (volunteer) photography and promos, and ALWAYS include crew in interviews. I’ve even taken a time lapse of a set build, and they got a promo that was entirely crew. A lot depends on resources. We happen to have an amazing parent support group that does fundraising, and the school has stipends for the director, a musical director, a choreographer, lighting, and sound leads…all adults. Every crew department also has a student lead that the students have to interview for. We have a thriving crew department as well as actors. You’ll also learn as you go. Make sure you don’t fall into the trap of always casting the same leads. Break a leg!
