Dramas changed over time.
One per district conventions (held in same venue at different times), different cast, homemade costumes mostly, supposed jws with good standing, right
Then very fancy sewn professionally costumes, with clothing props like shoewear and weapons. The elite among jws (those with money for costly costumes), took much time away from preaching for rehearsal and lip syncing.
Then one cast for several conventions. It became a status thing to be chosen.
Then technology came to be used, for films, only one cast (supposedly more experienced at acting) for all conventions in the US. Not sure how in other countries. So even more an elite group.
Very few,, current day situations, once again teaching jws to be like the Israelites or not, not like Jesus.
