Today, I'm prepping a costar side for a workshop with a tv casting director. The character is a prison guard giving testimony in a prison murder case. Straight forward enough, as costar sides almost always are, but to my reading, the side contains clues that suggest the character's circumstances give him a touch more personality--more attitude and point of view--than the situation necessarily suggests; there's room for a little humor, a little self-importance, a little uncertainty. The actor who played the role on tv didn't approach it that way: he kept it simple, 'just the facts, 'ma'am,' which is probably right; probably serves the stars acting in the scene with him; but may or may not serve the entertainment value of the scene.
I'll give it a crack and see how the CD takes it.
