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.

Why was he over the top?

Mays was born in 1931 in Westfield, Alabama. His father, Cat Mays, was a talented baseball player with the Negro team for the local iron plant. His mother, Annie Satterwhite, was a gifted basketball and track star in high school. His parents never married.
Mays began his major league career on a sour note, with no hits in his first 12 at bats. On his 13th at-bat, however, he hit a towering home run over the left field roof of the Polo Grounds off of future Hall of Famer Warren Spahn. Spahn later joked, "I'll never forgive myself. We might have gotten rid of Willie forever if I'd only struck him out." Mays's batting average improved steadily throughout the rest of the season. Although his .274 average, 68 RBI and 20 homers (in 121 games) were among the lowest of his career, he still won the 1951 Rookie of the Year Award. During the Giants' comeback in August and September 1951 to tie the Dodgers in the pennant race, Mays' fielding and strong throwing arm were instrumental to several important Giants victories. Mays was in the on-deck circle when Bobby Thomson hit the Shot Heard 'Round the World against Ralph Branca and the Brooklyn Dodgers to win the three-game playoff 2-1 after the teams were tied at the end of the regular season. The Giants went on to meet the New York Yankees in the 1951 World Series. In Game 1, Mays, Hank Thompson and Hall of Famer Monte Irvin comprised the first all-African-American outfield in major league history four years after the color line was broken. Mays hit poorly while the Giants lost the series 4-2. The six-game set was the only time that Mays and retiring Yankee ace Joe DiMaggio would compete against each other. Mays was a popular figure in Harlem. Magazine photographers were fond of chronicling his participation in local stickball games with kids. It was said that in the urban game of hitting a rubber ball with an adapted broomstick handle, Mays could hit a shot that measured "six sewers" (the distance of six consecutive New York City manhole covers, nearly 300 feet).

Did he go on to become very successful with his batting?
Although his .274 average, 68 RBI and 20 homers (in 121 games) were among the lowest of his career, he still won the 1951 Rookie of the Year Award.
