Answer the question at the end by quoting:

Zelig is a 1983 American mockumentary film written and directed by Woody Allen and starring Allen and Mia Farrow. Allen plays Leonard Zelig, a nondescript enigma, who, out of his desire to fit in and be liked, takes on the characteristics of strong personalities around him. The film, presented as a documentary, recounts his intense period of celebrity in the 1920s and includes analyses from contemporary intellectuals. Zelig was photographed and narrated in the style of 1920s black-and-white newsreels, which are interwoven with archival footage from the era and re-enactments of real historical events.
Allen used newsreel footage and inserted himself and other actors into the footage using bluescreen technology. To provide an authentic look to his scenes, Allen and cinematographer Gordon Willis used a variety of techniques, including locating some of the antique film cameras and lenses used during the eras depicted in the film, and even going so far as to simulate damage, such as crinkles and scratches, on the negatives to make the finished product look more like vintage footage. The virtually seamless blending of old and new footage was achieved almost a decade before digital filmmaking technology made such techniques in films like Forrest Gump (1994) and various television advertisements much easier to accomplish. The film uses cameo appearances by real figures from academia and other fields for comic effect. Contrasting the film's vintage black-and-white film footage, these persons appear in color segments as themselves, commenting in the present day on the Zelig phenomenon as if it really happened. They include essayist Susan Sontag, psychoanalyst Bruno Bettelheim, Nobel Prize-winning novelist Saul Bellow, political writer Irving Howe, historian John Morton Blum, and the Paris nightclub owner Bricktop. Also appearing in the film's vintage footage are Charles Lindbergh, Al Capone, Clara Bow, William Randolph Hearst, Marion Davies, Charlie Chaplin, Josephine Baker, Fanny Brice, Carole Lombard, Dolores del Rio, Adolf Hitler, Joseph Goebbels, Hermann Goring, James Cagney, Jimmy Walker, Lou Gehrig, Babe Ruth, Adolphe Menjou, Claire Windsor, Tom Mix, Marie Dressler, Bobby Jones, and Pope Pius XI. In the time it took to complete the film's special effects, Allen filmed A Midsummer Night's Sex Comedy and Broadway Danny Rose.

IN: Percy Tyrone Sledge (November 25, 1940 - April 14, 2015) was an American R&B, soul and gospel singer. He is best known for the song "When a Man Loves a Woman", a No. 1 hit on both the Billboard Hot 100 and R&B singles charts in 1966. It was awarded a million-selling, Gold-certified disc from the RIAA. Having previously worked as a hospital orderly in the early 1960s, Sledge achieved his strongest success in the late 1960s and early 1970s with a series of emotional soul songs.

Sledge's career enjoyed a renaissance in the 1980s when "When a Man Loves a Woman" re-entered the UK Singles Chart, peaking at No. 2 behind the reissued Ben E. King classic "Stand by Me", after being used in a Levi's commercial. In the early 1990s, Michael Bolton brought "When a Man Loves a Woman" back into the limelight again on his hit album Time, Love, & Tenderness. On the week of November 17 to November 23, 1991, Bolton's version also hit No. 1 on the Billboard Hot 100 singles chart, exactly 25 1/2 years to the week after Percy's did in 1966. In 1994, Saul Davis and Barry Goldberg produced Sledge's album, Blue Night, for Philippe Le Bras' Sky Ranch label and Virgin Records. It featured Bobby Womack, Steve Cropper, and Mick Taylor among others. Blue Night received a Grammy nomination for Best Contemporary Blues Album, Vocal or Instrumental, and in 1996 it won the W.C. Handy Award for best soul or blues album. In 2004, Davis and Goldberg also produced the Shining Through the Rain album, which preceded his induction into the Rock & Roll Hall of Fame. Songs on the CD were written by Mikael Rickfors, Steve Earle, the Bee Gees, Carla Olson, Denny Freeman, Allan Clarke and Jackie Lomax. The same year Percy recorded a live album with his band Sunset Drive entitled Percy Sledge and Sunset Drive - Live in Virginia on WRM Records produced by Warren Rodgers. In May 2007, Percy was inducted into The Louisiana Music Hall Of Fame in his home city of Baton Rouge, LA. In December 2010, Rhino Handmade issued a four-CD retrospective, The Atlantic Recordings, which covers all of the issued Atlantic masters, as well as many of the tracks unissued in the United States (although some were simply the mono versions of songs originally issued in stereo; Disc 1 comprises Sledge's first two LPs which were not recorded on stereo equipment). In 2011 Sledge toured with Sir Cliff Richard during his Soulicious tour, performing "I'm Your Puppet".
