Question:
Nilsson was born in Bedford-Stuyvesant, Brooklyn in 1941. His paternal grandparents were Swedish circus performers and dancers, especially known for their "aerial ballet" (which is the title of one of Nilsson's albums). His maternal grandparents were the cornerstone of his young life. While his grandmother played piano, his grandfather Charlie supported the family in a tiny railroad apartment on Jefferson St in Brooklyn.
Nilsson's disregard for commercialism in favor of artistic satisfaction showed itself in his next release, A Little Touch of Schmilsson in the Night (1973). Performing a selection of pop standards by the likes of Berlin, Kalmar and Ruby, Nilsson sang in front of an orchestra arranged and conducted by veteran Gordon Jenkins in sessions produced by Derek Taylor. This musical endeavor did not do well commercially. The session was filmed, and broadcast as a television special by the BBC in the UK.  1973 found Nilsson back in California, and when John Lennon moved there during his separation from Yoko Ono, the two musicians rekindled their earlier friendship. Lennon was intent upon producing Nilsson's next album, much to Nilsson's delight. However, their time together in California became known much more for heavy drinking than it did for musical collaboration. In a widely publicized incident, the two were ejected from the Troubadour nightclub in West Hollywood for drunken heckling of the Smothers Brothers.  To make matters worse, at a late night party and jam session during the recording of the album, attended by Lennon, McCartney, Danny Kortchmar, and other musicians, Nilsson ruptured a vocal cord, but he hid the injury for fear that Lennon would call a halt to the production. The resulting album was Pussy Cats. In an effort to clean up, Lennon, Nilsson and Ringo Starr first rented a house together, then Lennon and Nilsson left for New York. After the relative failure of his latest two albums, RCA Records considered dropping Nilsson's contract. In a show of friendship, Lennon accompanied Nilsson to negotiations, and both intimated to RCA that Lennon and Starr might want to sign with them, once their Apple Records contracts with EMI expired in 1975, but would not be interested if Nilsson were no longer with the label. RCA took the hint and re-signed Nilsson (adding a bonus clause, to apply to each new album completed), but neither Lennon nor Starr signed with RCA.  Nilsson's voice had mostly recovered by his next release, Duit on Mon Dei (1975), but neither it nor its follow-ups, Sandman and ...That's the Way It Is (both 1976), met with chart success. Finally, Nilsson recorded what he later considered to be his favorite album Knnillssonn (1977). With his voice strong again, and his songs exploring musical territory reminiscent of Harry or The Point!, Nilsson anticipated Knnillssonn to be a comeback album. RCA seemed to agree, and promised Nilsson a substantial marketing campaign for the album. However, the death of Elvis Presley caused RCA to ignore everything except meeting demand for Presley's back catalog, and the promised marketing push never happened. This, combined with RCA releasing a Nilsson Greatest Hits collection without consulting him, prompted Nilsson to leave the label.

Answer the question at the end by quoting:

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.
In September 2005, Clooney explained his interest in the story to an audience at the New York Film Festival: "I thought it was a good time to raise the idea of using fear to stifle political debate." Having majored in journalism in college, Clooney was well-versed in the subject matter. His father, Nick Clooney, was a television journalist for many years, appearing as an anchorman in Cincinnati, Ohio, Salt Lake City, Utah, Los Angeles, California, and Buffalo, New York. The elder Clooney also ran for Congress in 2004.  George Clooney was paid $1 each for writing, directing, and acting in Good Night, and Good Luck., which cost $7.5 million to make. Due to an injury he received on the set of Syriana a few months earlier, Clooney could not pass the tests to be insured. He then mortgaged his own house in Los Angeles in order to make the film. Dallas Mavericks owner Mark Cuban and former eBay president Jeff Skoll invested money in the project as executive producers. The film ultimately grossed more than $54 million worldwide.  The CBS offices and studios seen in the movie were all sets on a soundstage. To accomplish a pair of scenes showing characters going up an elevator, different "floors" of the building were laid out on the same level. The "elevator" was actually built on a large turntable at the intersection of the two floor sets, and rotated once the doors were closed. When the doors reopened, the actors appeared to be in a different location. In doing so, the movie exercised a bit of dramatic license--the CBS executive offices at the time were located at 485 Madison Avenue. CBS News was located in an office building just north of Grand Central Terminal (demolished and now the site of the Met Life Building); and the See It Now studio was located in Grand Central Terminal itself, above the waiting room. For dramatic effect, all three areas were depicted as being in the same building.  Clooney and producer Grant Heslov decided to use only archival footage of Joseph McCarthy in his depiction. As all of that footage was black-and-white, that determined the color scheme of the film. A young Robert Kennedy is also shown in the movie during McCarthy's hearing sessions. He was then a staff member on the Senate subcommittee chaired by McCarthy.
