Good Night, and Good Luck is a 2005 American historical drama film directed by George Clooney and starring David Strathairn, George Clooney, Robert Downey, Jr., Patricia Clarkson and Jeff Daniels. The movie was written by Clooney and Grant Heslov (both of whom also have acting roles in the film) and portrays the conflict between veteran radio and television journalist Edward R. Murrow and U.S. Senator Joseph McCarthy of Wisconsin, especially relating to the anti-Communist Senator's actions with the Senate Permanent Subcommittee on Investigations. Although released in black and white, Good Night, and Good Luck was filmed on color film stock but on a greyscale set, and was color corrected to black and white during post-production. It focuses on the theme of media responsibility, and also addresses what occurs when the media offer a voice of dissent from government policy.

The film was critically acclaimed upon release. It was named "Best Reviewed Film of 2005 in Limited Release" by Rotten Tomatoes, where it achieved a 93% positive review rating, based on reviews from 217 critics. The film received six Academy Award nominations, including Best Picture, Director (Clooney), and Actor (Strathairn).  Roger Ebert, in his Chicago Sun-Times review, contends that "the movie is not really about the abuses of McCarthy, but about the process by which Murrow and his team eventually brought about his downfall (some would say his self-destruction). It is like a morality play, from which we learn how journalists should behave. It shows Murrow as fearless, but not flawless." Margaret Pomeranz and David Stratton from the ABC show At the Movies each gave the film five stars, making Good Night, and Good Luck the only other film besides Brokeback Mountain to receive such a score from the hosts in 2005. Both described the film as "beautiful" but also praised Clooney for the film's importance. Margaret commented that "[The film] is so important, because it's about things that are really vital today, like the responsibility of the press and examining the press' role in forming opinion." David noted "Though [the film] is in black-and-white, there's nothing monochromatic about Clooney's passion for his subject or the importance of his message."  Jack Shafer, a libertarian-leaning columnist for the online magazine Slate, accused the film of continuing what he characterizes as the hagiography of Murrow. Clooney's film gives the impression that Murrow brought down McCarthy single-handedly, while Shafer notes that in reality much of the mainstream media, many Democrats and some of McCarthy's Republican peers were condemning him before Murrow. Furthermore, Shafer writes, evidence obtained via the declassified Venona espionage program confirmed that many Soviet agents and sympathizers were in fact in positions of influence in the U.S. government, a disclosure the film entirely overlooks: "Clooney and company ignore the material that might argue against their simple-minded thesis about Murrow, the era, and the press to produce an after-school special".  One complaint about the film among test audiences was their belief that the actor playing McCarthy was too over the top, not realizing that the film used actual archive footage of McCarthy himself.
