George Clooney's Good Night, and Good Luck play, an ode to old-school, broadcast journalism, is set to air on CNN.

"I can't tell you how exciting it is to do something that's never been done," Clooney said in a press release Thursday.

"CNN is the perfect place to bring this story of courage to so many more people than we could have ever hoped. Live TV. No net. Buckle up everyone."

Clooney plays CBS News legend and free-press champion Edward R. Murrow, who was known for his showdowns with U.S. Sen. Joseph McCarthy, who accused -- many times falsely -- high-profile people of being communists or under Soviet influence in the 1940s and '50s.
