Some context: Fred Astaire (born Frederick Austerlitz; May 10, 1899 - June 22, 1987) was an American dancer, singer, actor, choreographer and television presenter. He is widely regarded as one of the most influential dancers in the history of film and television musicals. His stage and subsequent film and television careers spanned a total of 76 years, during which he starred in more than 10 Broadway and London musicals, made 31 musical films, 4 television specials, and issued numerous recordings.
Retirement didn't last long. Astaire returned to the big screen to replace the injured Kelly in Easter Parade (1948) opposite Judy Garland, Ann Miller, and Peter Lawford and for a final reunion with Rogers (replacing Judy Garland) in The Barkleys of Broadway (1949). Both of these films revived Astaire's popularity and in 1950 he starred in two musicals - one for M-G-M - Three Little Words with Vera-Ellen and Red Skelton and one on loan-out to Paramount - Let's Dance with Betty Hutton. While Three Little Words did quite well at the box office, Let's Dance was a financial disappointment. Royal Wedding (1951) with Jane Powell and Peter Lawford proved to be very successful, but The Belle of New York (1952) with Vera-Ellen was a critical and box-office disaster. The Band Wagon (1953), which is considered to be one of the finest musicals ever made, received rave reviews from critics and drew huge crowds. But because of its excessive cost, it failed to make a profit on its first release. Soon after, Astaire, along with all the other remaining stars at M-G-M, was let go from his contract because of the advent of television and the downsizing of film production. In 1954, Astaire was about to start work on a new musical, Daddy Long Legs (1955) with Leslie Caron at 20th Century Fox, when his wife Phyllis became ill and suddenly died of lung cancer. Astaire was so bereaved that he wanted to shut down the picture and offered to pay the production costs out of his own pocket. However, Johnny Mercer (the film's composer) and Fox studio executives convinced him that work would be the best thing for him at that time. When Daddy Long Legs was released in 1955, it did only moderately well at the box office. His next film for Paramount, Funny Face (1957), teamed him with Audrey Hepburn and Kay Thompson and despite the sumptuousness of the production and the strong reviews from critics, it failed to make back its cost. Similarly, Astaire's next project - his final musical at M-G-M, Silk Stockings (1957), in which he co-starred with Cyd Charisse, also lost money at the box office. As a result, Astaire withdrew from motion pictures for two years.  During 1952, Astaire recorded The Astaire Story, a four-volume album with a quintet led by Oscar Peterson. The album, produced by Norman Granz, provided a musical overview of Astaire's career. The Astaire Story later won the Grammy Hall of Fame Award in 1999, a special Grammy award to honor recordings that are at least twenty-five years old and that have "qualitative or historical significance."  His legacy at this point was 30 musical films in 25 years. Afterwards, Astaire announced that he was retiring from dancing in film to concentrate on dramatic acting, scoring rave reviews for the nuclear war drama On the Beach (1959).
Why did Astaire come out of retirement?
A: Astaire returned to the big screen to replace the injured Kelly in Easter Parade (1948) opposite Judy Garland, Ann Miller, and Peter Lawford
Some context: The Spice Girls are an English pop girl group formed in 1994. The group originally consisted of Melanie Brown ("Scary Spice"), Melanie Chisholm ("Sporty Spice"), Emma Bunton ("Baby Spice"), Geri Halliwell ("Ginger Spice"), and Victoria Beckham, nee Adams ("Posh Spice"). They were signed to Virgin Records and released their debut single "Wannabe" in 1996, which hit number one in 37 countries and established them as a global phenomenon. Their debut album Spice sold more than 31 million copies worldwide, becoming the best-selling album by a female group in history.
The phrase "girl power" put a name to a social phenomenon, but the slogan was met with mixed reactions. The phrase was a label for the particular facet of post classical neo-feminist empowerment embraced by the band: that a sensual, feminine appearance and equality between the sexes need not be mutually exclusive. This concept was by no means original in the pop world: both Madonna and Bananarama had employed similar outlooks. The phrase itself had also appeared in a few songs by British girl groups and bands since at least 1987; most notably, it was the name of British pop duo Shampoo's 1996 single and album, later credited by Halliwell as the inspiration for the Spice Girls' mantra.  However, it was not until the emergence of the Spice Girls in 1996 with "Wannabe", that the concept of "girl power" exploded onto the common consciousness. The phrase was regularly uttered by all five members--although most closely associated with Halliwell--and was often delivered with a peace sign. The slogan also featured on official Spice Girls merchandise and on some of the outfits the group members wore. The Spice Girls' version was distinctive. Its message of empowerment appealed to young girls, adolescents and adult women, and it emphasised the importance of strong and loyal friendship among females.  In all, the focused, consistent presentation of "girl power" formed the centrepiece of their appeal as a band. Some commentators credit the Spice Girls with reinvigorating mainstream feminism--popularized as "girl power"--in the 1990s, with their mantra serving as a gateway to feminism for their young fans. On the other hand, some critics dismissed it as no more than a shallow marketing tactic, while others took issue with the emphasis on physical appearance, concerned about the potential impact on self-conscious and/or impressionable youngsters. Regardless, the phrase became a cultural phenomenon, adopted as the mantra for millions of girls and even making it into the Oxford English Dictionary. In summation of the concept, author Ryan Dawson said, "The Spice Girls changed British culture enough for Girl Power to now seem completely unremarkable."  The Spice Girls' debut single "Wannabe" has been hailed as an "iconic girl power anthem". In 2016, the United Nations' Global Goals "#WhatIReallyReallyWant" campaign filmed a global remake of the original music video for "Wannabe" to highlight gender inequality issues faced by women across the world. The video, which was launched on YouTube and ran in movie theatres internationally, featured British girl group M.O, Canadian "viral sensation" Taylor Hatala, Nigerian-British singer Seyi Shay and Bollywood actress Jacqueline Fernandez lip-syncing to the song in various locations around the world. In response to the remake, Beckham said, "How fabulous is it that after 20 years the legacy of the Spice Girls' girl power is being used to encourage and empower a whole new generation?"  At the 43rd People's Choice Awards in January 2017, American actress Blake Lively dedicated her "Favorite Dramatic Movie Actress" award to "girl power" in her acceptance speech, and credited the Spice Girls, saying: "What was so neat about them was that they're all so distinctly different, and they were women, and they owned who they were, and that was my first introduction into girl power."
