"Good Night, and Good Luck" originated as a 2005 film starring George Clooney, David Strathairn, Patricia Clarkson and Robert Downey Jr. The film tells the story of broadcast journalist Edward R. Murrow's mission to challenge Senator Joseph McCarthy.

In taking "Good Night, and Good Luck" from Broadway to our living rooms, Clooney returns, once again, to the medium that made him a star - and that he still believes can make an impact.

Viewers tuning in to see George Clooney star in Good Night, and Good Luck live on CNN were surprised to recognize another actor in the production.
