Chicargo was directed and choreographed by Rob Marshall and not Baz Luhrmann.

Mark Anthony "Baz" Luhrmann (born 17 September 1962) is an Australian film director, screenwriter and producer best known for The Red Curtain Trilogy, comprising his romantic comedy film Strictly Ballroom (1992), the romantic drama Romeo + Juliet (1996), and the pastiche-jukebox musical Moulin Rouge! (2001). His 2008 film Australia is an epic historical romantic drama film starring Hugh Jackman and Nicole Kidman. His 2013 drama The Great Gatsby, based on F. Scott Fitzgerald's 1925 novel of the same name, stars Leonardo DiCaprio (whom he also used in Romeo + Juliet) and Tobey Maguire.

Luhrmann has cited Italian grand opera as a major influence on his work and has also given a nod to other theatrical styles, such as Bollywood films, as having influenced his style. Luhrmann was a ballroom dancer as a child and his mother taught ballroom dancing which was an inspiration for Strictly Ballroom.
