Acclaimed film and television actor George Clooney previewed his upcoming Broadway debut in Good Night, and Good Luck and admitted that he feels nervous about stepping on the stage, reported Reuters.

A two-time Oscar winner, Clooney said he has not done a live theatre show since 1986. "I haven't done a play in 40 years ... so it's terrifying," the actor told reporters in New York at a press conference about the theatre production. "Yes, George Clooney gets nervous."

Clooney is the co-writer and star of Good Night, and Good Luck, a historical drama about 1950s American television news. The play is adapted from Clooney's 2005 film of the same name. It depicts the conflict between broadcast journalist Edward R. Murrow and Senator Joseph McCarthy, and the senator's anti-communist witch hunt.

"The fun part about this is we get to do a play about a subject matter that's very close to our hearts, which is about everything that you guys all do, which is telling the truth and holding truth to power," Clooney told reporters. "It's not a civics lesson," he added. "It's entertainment. And we're very excited to start." Good Night, and Good Luck runs on Broadway from March 12 to June 8.
