I'm looking for shows, either full-length or one-acts that have primarily youngers characters between say 18 and 30. I read a lot of shows on samuel french or dramatists, but they really don't tell you age range of the characters. I know one should pick an interesting play and then cast it accordingly, but there's a group of actors that I wanna work with and I want something where they're not all playing 45+ characters.

Any and all suggestions welcome

i would try the living by anthony clarvoe, a fascinating look into the 1600's plague. It was one of the best plays i think i ever put on, yet you'll need a budget that can keep up with the scripts called for set, costume, etc.
