"I'll Make a Man Out of You" is a song written by composer Matthew Wilder and lyricist David Zippel for Walt Disney Pictures' animated film Mulan (1998). Appearing on the film's soundtrack Mulan: An Original Walt Disney Records Soundtrack, "I'll Make a Man Out of You" is performed by American singer Donny Osmond as the singing voice of Captain Li Shang in lieu of American actor BD Wong, who provides the character's speaking voice. The song also features contributions from Lea Salonga as the singing voice of Mulan, Eddie Murphy as Mushu, and Harvey Fierstein, Jerry Tondo and Wilder himself as Yao, Chien-Po and Ling, respectively. In addition, Mushu has a speaking line unlike the other characters in the song. "I'll Make a Man Out of You" was written to replace the song "We'll Make a Man of You" after the film's original songwriter Stephen Schwartz departed from the project in favor of working on DreamWorks' The Prince of Egypt (1998). Wilder and Zippel were inspired to complete the song after conceiving its ironic title, and the initial draft of the track was immediately approved by Disney. Prior to Mulan, Osmond had auditioned for the role of Hercules in Disney's Hercules (1997), a role for which he was ultimately turned down by the directors because they felt that he sounded too old. Disney eventually cast Osmond as the singing voice of Shang because his singing voice is similar to Wong's speaking voice. An up-tempo military-style song that incorporates both Eastern and Western musical styles, "I'll Make a Man Out of You" is performed by Shang during a rigorous training montage in which his young, inexperienced soldiers attempt to justify their worth. The song's title is considered ironic because Mulan, who relies on intelligence, ultimately proves more competent than her male comrades, including Captain Li Shang, who takes a liking to her, while its lyrics explore hyper-masculinity contradicted with Mulan's gender. "I'll Make a Man Out of You" has received mostly positive reviews from film and music critics, some of whom dubbed it the film's best song, while praising Osmond's performance. Critics have also drawn comparisons between the song and Disney's Hercules, while likening Mulan's role and transformation to actress Demi Moore's performance as Lieutenant Jordan O'Neil in the film G. I. Jane (1997). The song has since appeared on several "best of" Disney songs lists, including those of Total Film and the New York Post. Discussed by film critics, film historians, academic journalists and feminists, the song has gone on to be recorded and covered in several different languages—namely Mandarin, Cantonese and Spanish—by entertainers Jackie Chan and Cristian Castro, respectively.
