If Only More Theatres Had This Law

From "Oil and Water, Or How a Director Taught the Brilliant Old Dogs of Steppenwolf Some New Tricks" by Tina Landua, in this month's American Theatre:

"There's another thing I've learned from Steppenwolf. It's not: "Yes, and..." or "The same only different," but it too possesses a quirky and self-explantory name. We call it: "I cry bullshit." I learned this from the likes of Tom and Amy, Laurie Metcalf, Gary Sinise, Terry Kinney and Jeff Perry. It's a favor the ensemble does for each other, and they've developed this technique over 25 years together in basements, churches, and now in their three performance spaces on North Halsted Street in Chicago. If you're watching rehearsals and something happens onstage that is false, contrived, not believable (it could be a move, an acting choice, a line) you are encouraged (not required) by Steppenwolf Law to raise your hand as you would in class and call out: "I cry bullshit!"
