This is the moment…
Improv consists of short scenes… even long-form improv consists of relatively short scenes (when compared to one life time). Each short scene is a moment in which players enter the stage and plays out a short snippet of another person’s life. The character you are playing lived before you played them and they’ll live on after you are done with the stage (in most cases).
The key is to make this a pivotal moment in the characters life. If your character has been picked on at school for years… this is the moment they stand up to that. If a husband and wife have been avoiding fighting about something for years, this is the moment that the fight reaches an apex.
An improv scene is not the time for avoidance… take scene themes and dialogue head on and make THIS a powerful moment in your characters life.
