Have you seen Actor's Nightmare, directed by Zoe Galvez?  It's a show we've done for the first time during the Covid shutdown and it's shown up again and again in our line-up.  The premise?  A series of scenes where an improviser is paired up with a scripted actor.  The actor shows up with lines memorized from real scenes in real plays and movies, and the improvisers are faced with the challenge of making up their half of the dialogue, never knowing where the scripted scene is going!
