We want to fill our blank stages with imagined environment. We want to engage physically in that environment to help visualize the imagined. And – most importantly – we want to be emotionally affected by where we are and what we’re doing. That’s Improv As Improv Does Best.
Our fellow player(s) and how they emotionally affect our characters is important. But engaging heir scene partner is not where improvisers struggle. One’s scene partner is actually active on stage – his/her presence doesn’t have to be imagined – so too often players give 100% of their attention on their partner and ignore physically engaging the environment.
Like the “We gotta…” and “That’s my…” initiation exercises, the “I was just…” drill helps connect emotion to active endowments.
