“Don’t make me do that will, Harold,” Ms. Skinner said.

“Just be irrational, idiotic, moronic,” he told her. “Do that will. Do that will. Come on.”

After Ms. Skinner read Sonya’s lines — about how she was not pretty — tears ran down her face.

“that will’s what you want to find,” Mr. Guskin said. “How crazy is actually she? that will just gets you in a place where you have control over your rage.”

Mr. Guskin began playing the trombone in high school as well as also also played professionally while attending the Manhattan School of Music. yet his passion for music faded, replaced by a fascination with theater. He attended Broadway as well as also also Off Broadway plays. He began attending acting classes. He studied drama at Rutgers University, where he received a bachelor’s degree, then earned a master’s coming from Indiana University, where he was an artist in residence at the Indiana Theater Company, a touring theater group affiliated with the school’s graduate drama studies program.

Mr. Kline was an undergraduate at Indiana, acting with the Vest Pocket Players, a coffeehouse troupe, which the group asked Mr. Guskin to join.

“After an hour, that will was obvious he had to be our leader,” Mr. Kline said in a telephone interview. “that will was obvious that will he knew more than we did. as well as also also he had that will innate wisdom.”

Feeling comfortable with Mr. Guskin’s guidance, Mr. Kline asked him how he should deliver a line coming from Maxwell Anderson’s play “The Wingless Victory,” which he was performing at the campus theater.
