I've noticed that lately, I've played a bunch of characters who feature prominently in Act One and then don't do much of anything later on. It's surprising how many there are.
The ones that immediately spring to mind for me are Fantine in Les Mis, Mufasa in The Lion King, and the Wolf in Into the Woods (I know on Broadway, it's the same actor[s] playing the prince[s], but in both amateur productions I've seen, they've been different actors).
Who else gets to chill backstage for the majority of an act?
